start_ns(prefix, uri)

class lxml.etree.CDATA(data)

Bases: object

CDATA factory. This factory creates an opaque data object that can be used to set Element text. The usual way to use it is:

>>> el = Element('content')
>>> el.text = CDATA('a string')

>>> print(el.text)
a string
>>> print(tostring(el, encoding="unicode"))
<content><![CDATA[a string]]></content>

class lxml.etree.CommentBase

Bases: _Comment

All custom Comment classes must inherit from this one.

To create an XML Comment instance, use the Comment() factory.

Subclasses must not override __init__ or __new__ as it is absolutely undefined when these objects will be created or destroyed. All persistent state of Comments must be stored in the underlying XML. If you really need to initialize the object after creation, you can implement an _init(self) method that will be called after object creation.

_init(self): Called after object initialisation. Custom subclasses may override this if they recursively call _init() in the superclasses.

addnext(self, element)

Adds the element as a following sibling directly after this element.

This is normally used to set a processing instruction or comment after the root node of a document. Note that tail text is automatically discarded when adding at the root level.

addprevious(self, element)

Adds the element as a preceding sibling directly before this element.

This is normally used to set a processing instruction or comment before the root node of a document. Note that tail text is automatically discarded when adding at the root level.

append(self, value)

clear(self, keep_tail=False)

Resets an element. This function removes all subelements, clears all attributes and sets the text and tail properties to None.

Pass keep_tail=True to leave the tail text untouched.

cssselect(expr, *, translator='xml')

Run the CSS expression on this element and its children, returning a list of the results.

Equivalent to lxml.cssselect.CSSSelect(expr)(self) – note that pre-compiling the expression can provide a substantial speedup.

extend(self, elements): Extends the current children by the elements in the iterable.

find(self, path, namespaces=None)

Finds the first matching subelement, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

findall(self, path, namespaces=None)

Finds all matching subelements, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

findtext(self, path, default=None, namespaces=None)

Finds text for the first matching subelement, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

get(self, key, default=None)

getchildren(self)

Returns all direct children. The elements are returned in document order.

Deprecated:: Note that this method has been deprecated as of ElementTree 1.3 and lxml 2.0. New code should use list(element) or simply iterate over elements.

getiterator(self, tag=None, *tags)

Returns a sequence or iterator of all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags, see iter.

Deprecated:: Note that this method is deprecated as of ElementTree 1.3 and lxml 2.0. It returns an iterator in lxml, which diverges from the original ElementTree behaviour. If you want an efficient iterator, use the element.iter() method instead. You should only use this method in new code if you require backwards compatibility with older versions of lxml or ElementTree.

getnext(self): Returns the following sibling of this element or None.

getparent(self): Returns the parent of this element or None for the root element.

getprevious(self): Returns the preceding sibling of this element or None.

getroottree(self)

Return an ElementTree for the root node of the document that contains this element.

This is the same as following element.getparent() up the tree until it returns None (for the root element) and then build an ElementTree for the last parent that was returned.

index(self, child, start=None, stop=None)

Find the position of the child within the parent.

This method is not part of the original ElementTree API.

insert(self, index, value)

items(self)

iter(self, tag=None, *tags)

Iterate over all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags: pass "{ns}localname" as tag. Either or both of ns and localname can be * for a wildcard; ns can be empty for no namespace. "localname" is equivalent to "{}localname" (i.e. no namespace) but "*" is "{*}*" (any or no namespace), not "{}*".

You can also pass the Element, Comment, ProcessingInstruction and Entity factory functions to look only for the specific element type.

Passing multiple tags (or a sequence of tags) instead of a single tag will let the iterator return all elements matching any of these tags, in document order.

iterancestors(self, tag=None, *tags)

Iterate over the ancestors of this element (from parent to parent).

Can be restricted to find only elements with specific tags, see iter.

iterchildren(self, tag=None, *tags, reversed=False)

Iterate over the children of this element.

As opposed to using normal iteration on this element, the returned elements can be reversed with the ‘reversed’ keyword and restricted to find only elements with specific tags, see iter.

iterdescendants(self, tag=None, *tags)

Iterate over the descendants of this element in document order.

As opposed to el.iter(), this iterator does not yield the element itself. The returned elements can be restricted to find only elements with specific tags, see iter.

iterfind(self, path, namespaces=None)

Iterates over all matching subelements, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

itersiblings(self, tag=None, *tags, preceding=False)

Iterate over the following or preceding siblings of this element.

The direction is determined by the ‘preceding’ keyword which defaults to False, i.e. forward iteration over the following siblings. When True, the iterator yields the preceding siblings in reverse document order, i.e. starting right before the current element and going backwards.

Can be restricted to find only elements with specific tags, see iter.

itertext(self, tag=None, *tags, with_tail=True)

Iterates over the text content of a subtree.

You can pass tag names to restrict text content to specific elements, see iter.

You can set the with_tail keyword argument to False to skip over tail text.

keys(self)

makeelement(self, _tag, attrib=None, nsmap=None, **_extra): Creates a new element associated with the same document.

remove(self, element): Removes a matching subelement. Unlike the find methods, this method compares elements based on identity, not on tag value or contents.

replace(self, old_element, new_element): Replaces a subelement with the element passed as second argument.

set(self, key, value)

values(self)

xpath(self, _path, namespaces=None, extensions=None, smart_strings=True, **_variables): Evaluate an xpath expression using the element as context node.

attrib

base

The base URI of the Element (xml:base or HTML base URL). None if the base URI is unknown.

Note that the value depends on the URL of the document that holds the Element if there is no xml:base attribute on the Element or its ancestors.

Setting this property will set an xml:base attribute on the Element, regardless of the document type (XML or HTML).

nsmap

Namespace prefix->URI mapping known in the context of this Element. This includes all namespace declarations of the parents.

Note that changing the returned dict has no effect on the Element.

prefix: Namespace prefix or None.

sourceline: Original line number as found by the parser or None if unknown.

tag

tail: Text after this element’s end tag, but before the next sibling element’s start tag. This is either a string or the value None, if there was no text.

text

class lxml.etree.CustomElementClassLookup(self, fallback=None)

Bases: FallbackElementClassLookup

Element class lookup based on a subclass method.

You can inherit from this class and override the method:

lookup(self, type, doc, namespace, name)

to lookup the element class for a node. Arguments of the method: * type: one of ‘element’, ‘comment’, ‘PI’, ‘entity’ * doc: document that the node is in * namespace: namespace URI of the node (or None for comments/PIs/entities) * name: name of the element/entity, None for comments, target for PIs

If you return None from this method, the fallback will be called.

lookup(self, type, doc, namespace, name)

set_fallback(self, lookup): Sets the fallback scheme for this lookup method.

fallback

class lxml.etree.DTD(self, file=None, external_id=None)

Bases: _Validator

A DTD validator.

Can load from filesystem directly given a filename or file-like object. Alternatively, pass the keyword parameter external_id to load from a catalog.

_append_log_message(domain, type, level, line, message, filename)

_clear_error_log()

assertValid(self, etree): Raises DocumentInvalid if the document does not comply with the schema.

assert_(self, etree): Raises AssertionError if the document does not comply with the schema.

elements()

entities()

iterelements()

iterentities()

validate(self, etree)

Validate the document using this schema.

Returns true if document is valid, false if not.

error_log: The log of validation errors and warnings.

external_id

name

system_url

class lxml.etree.DocInfo

Bases: object

Document information provided by parser and DTD.

clear(): Removes DOCTYPE and internal subset from the document.

URL: The source URL of the document (or None if unknown).

doctype: Returns a DOCTYPE declaration string for the document.

encoding: Returns the encoding name as declared by the document.

externalDTD: Returns a DTD validator based on the external subset of the document.

internalDTD: Returns a DTD validator based on the internal subset of the document.

public_id

Public ID of the DOCTYPE.

Mutable. May be set to a valid string or None. If a DTD does not exist, setting this variable (even to None) will create one.

root_name: Returns the name of the root node as defined by the DOCTYPE.

standalone: Returns the standalone flag as declared by the document. The possible values are True (standalone='yes'), False (standalone='no' or flag not provided in the declaration), and None (unknown or no declaration found). Note that a normal truth test on this value will always tell if the standalone flag was set to 'yes' or not.

system_url

System ID of the DOCTYPE.

Mutable. May be set to a valid string or None. If a DTD does not exist, setting this variable (even to None) will create one.

xml_version: Returns the XML version as declared by the document.

class lxml.etree.ETCompatXMLParser(self, encoding=None, attribute_defaults=False, dtd_validation=False, load_dtd=False, no_network=True, ns_clean=False, recover=False, schema=None, huge_tree=False, remove_blank_text=False, resolve_entities=True, remove_comments=True, remove_pis=True, strip_cdata=True, target=None, compact=True)

Bases: XMLParser

An XML parser with an ElementTree compatible default setup.

See the XMLParser class for details.

This parser has remove_comments and remove_pis enabled by default and thus ignores comments and processing instructions.

close(self)

Terminates feeding data to this parser. This tells the parser to process any remaining data in the feed buffer, and then returns the root Element of the tree that was parsed.

This method must be called after passing the last chunk of data into the feed() method. It should only be called when using the feed parser interface, all other usage is undefined.

copy(self): Create a new parser with the same configuration.

feed(self, data)

Feeds data to the parser. The argument should be an 8-bit string buffer containing encoded data, although Unicode is supported as long as both string types are not mixed.

This is the main entry point to the consumer interface of a parser. The parser will parse as much of the XML stream as it can on each call. To finish parsing or to reset the parser, call the close() method. Both methods may raise ParseError if errors occur in the input data. If an error is raised, there is no longer a need to call close().

The feed parser interface is independent of the normal parser usage. You can use the same parser as a feed parser and in the parse() function concurrently.

makeelement(self, _tag, attrib=None, nsmap=None, **_extra): Creates a new element associated with this parser.

set_element_class_lookup(self, lookup=None)

Set a lookup scheme for element classes generated from this parser.

Reset it by passing None or nothing.

error_log: The error log of the last parser run.

feed_error_log

The error log of the last (or current) run of the feed parser.

Note that this is local to the feed parser and thus is different from what the error_log property returns.

resolvers: The custom resolver registry of this parser.

target

version: The version of the underlying XML parser.

class lxml.etree.ETXPath(self, path, extensions=None, regexp=True, smart_strings=True)

Bases: XPath

Special XPath class that supports the ElementTree {uri} notation for namespaces.

Note that this class does not accept the namespace keyword argument. All namespaces must be passed as part of the path string. Smart strings will be returned for string results unless you pass smart_strings=False.

error_log

path: The literal XPath expression.

class lxml.etree.ElementBase(*children, attrib=None, nsmap=None, **_extra)

Bases: _Element

The public Element class. All custom Element classes must inherit from this one. To create an Element, use the Element() factory.

BIG FAT WARNING: Subclasses must not override __init__ or __new__ as it is absolutely undefined when these objects will be created or destroyed. All persistent state of Elements must be stored in the underlying XML. If you really need to initialize the object after creation, you can implement an _init(self) method that will be called directly after object creation.

Subclasses of this class can be instantiated to create a new Element. By default, the tag name will be the class name and the namespace will be empty. You can modify this with the following class attributes:

TAG - the tag name, possibly containing a namespace in Clark notation
NAMESPACE - the default namespace URI, unless provided as part of the TAG attribute.
HTML - flag if the class is an HTML tag, as opposed to an XML tag. This only applies to un-namespaced tags and defaults to false (i.e. XML).
PARSER - the parser that provides the configuration for the newly created document. Providing an HTML parser here will default to creating an HTML element.

In user code, the latter three are commonly inherited in class hierarchies that implement a common namespace.

_init(self): Called after object initialisation. Custom subclasses may override this if they recursively call _init() in the superclasses.

addnext(self, element)

Adds the element as a following sibling directly after this element.

This is normally used to set a processing instruction or comment after the root node of a document. Note that tail text is automatically discarded when adding at the root level.

addprevious(self, element)

Adds the element as a preceding sibling directly before this element.

This is normally used to set a processing instruction or comment before the root node of a document. Note that tail text is automatically discarded when adding at the root level.

append(self, element): Adds a subelement to the end of this element.

clear(self, keep_tail=False)

Resets an element. This function removes all subelements, clears all attributes and sets the text and tail properties to None.

Pass keep_tail=True to leave the tail text untouched.

cssselect(expr, *, translator='xml')

Run the CSS expression on this element and its children, returning a list of the results.

Equivalent to lxml.cssselect.CSSSelect(expr)(self) – note that pre-compiling the expression can provide a substantial speedup.

extend(self, elements): Extends the current children by the elements in the iterable.

find(self, path, namespaces=None)

Finds the first matching subelement, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

findall(self, path, namespaces=None)

Finds all matching subelements, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

findtext(self, path, default=None, namespaces=None)

Finds text for the first matching subelement, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

get(self, key, default=None): Gets an element attribute.

getchildren(self)

Returns all direct children. The elements are returned in document order.

Deprecated:: Note that this method has been deprecated as of ElementTree 1.3 and lxml 2.0. New code should use list(element) or simply iterate over elements.

getiterator(self, tag=None, *tags)

Returns a sequence or iterator of all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags, see iter.

You should only use this method in new code if you require backwards compatibility with older versions of lxml or ElementTree.

getnext(self): Returns the following sibling of this element or None.

getparent(self): Returns the parent of this element or None for the root element.

getprevious(self): Returns the preceding sibling of this element or None.

getroottree(self)

Return an ElementTree for the root node of the document that contains this element.

This is the same as following element.getparent() up the tree until it returns None (for the root element) and then build an ElementTree for the last parent that was returned.

index(self, child, start=None, stop=None)

Find the position of the child within the parent.

This method is not part of the original ElementTree API.

insert(self, index, element): Inserts a subelement at the given position in this element

items(self): Gets element attributes, as a sequence. The attributes are returned in an arbitrary order.

iter(self, tag=None, *tags)

Iterate over all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags: pass "{ns}localname" as tag. Either or both of ns and localname can be * for a wildcard; ns can be empty for no namespace. "localname" is equivalent to "{}localname" (i.e. no namespace) but "*" is "{*}*" (any or no namespace), not "{}*".

You can also pass the Element, Comment, ProcessingInstruction and Entity factory functions to look only for the specific element type.

Passing multiple tags (or a sequence of tags) instead of a single tag will let the iterator return all elements matching any of these tags, in document order.

iterancestors(self, tag=None, *tags)

Iterate over the ancestors of this element (from parent to parent).

Can be restricted to find only elements with specific tags, see iter.

iterchildren(self, tag=None, *tags, reversed=False)

Iterate over the children of this element.

As opposed to using normal iteration on this element, the returned elements can be reversed with the ‘reversed’ keyword and restricted to find only elements with specific tags, see iter.

iterdescendants(self, tag=None, *tags)

Iterate over the descendants of this element in document order.

As opposed to el.iter(), this iterator does not yield the element itself. The returned elements can be restricted to find only elements with specific tags, see iter.

iterfind(self, path, namespaces=None)

Iterates over all matching subelements, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

itersiblings(self, tag=None, *tags, preceding=False)

Iterate over the following or preceding siblings of this element.

The direction is determined by the ‘preceding’ keyword which defaults to False, i.e. forward iteration over the following siblings. When True, the iterator yields the preceding siblings in reverse document order, i.e. starting right before the current element and going backwards.

Can be restricted to find only elements with specific tags, see iter.

itertext(self, tag=None, *tags, with_tail=True)

Iterates over the text content of a subtree.

You can pass tag names to restrict text content to specific elements, see iter.

You can set the with_tail keyword argument to False to skip over tail text.

keys(self): Gets a list of attribute names. The names are returned in an arbitrary order (just like for an ordinary Python dictionary).

makeelement(self, _tag, attrib=None, nsmap=None, **_extra): Creates a new element associated with the same document.

remove(self, element): Removes a matching subelement. Unlike the find methods, this method compares elements based on identity, not on tag value or contents.

replace(self, old_element, new_element): Replaces a subelement with the element passed as second argument.

set(self, key, value): Sets an element attribute. In HTML documents (not XML or XHTML), the value None is allowed and creates an attribute without value (just the attribute name).

values(self): Gets element attribute values as a sequence of strings. The attributes are returned in an arbitrary order.

xpath(self, _path, namespaces=None, extensions=None, smart_strings=True, **_variables): Evaluate an xpath expression using the element as context node.

attrib: Element attribute dictionary. Where possible, use get(), set(), keys(), values() and items() to access element attributes.

base

The base URI of the Element (xml:base or HTML base URL). None if the base URI is unknown.

Note that the value depends on the URL of the document that holds the Element if there is no xml:base attribute on the Element or its ancestors.

Setting this property will set an xml:base attribute on the Element, regardless of the document type (XML or HTML).

nsmap

Namespace prefix->URI mapping known in the context of this Element. This includes all namespace declarations of the parents.

Note that changing the returned dict has no effect on the Element.

prefix: Namespace prefix or None.

sourceline: Original line number as found by the parser or None if unknown.

tag: Element tag

tail: Text after this element’s end tag, but before the next sibling element’s start tag. This is either a string or the value None, if there was no text.

text: Text before the first subelement. This is either a string or the value None, if there was no text.

class lxml.etree.ElementChildIterator(self, node, tag=None, reversed=False)

Bases: _ElementMatchIterator

Iterates over the children of an element.

class lxml.etree.ElementClassLookup(self)

Bases: object

Superclass of Element class lookups.

class lxml.etree.ElementDefaultClassLookup(self, element=None, comment=None, pi=None, entity=None)

Bases: ElementClassLookup

Element class lookup scheme that always returns the default Element class.

The keyword arguments element, comment, pi and entity accept the respective Element classes.

comment_class

element_class

entity_class

pi_class

class lxml.etree.ElementDepthFirstIterator(self, node, tag=None, inclusive=True)

Bases: object

Iterates over an element and its sub-elements in document order (depth first pre-order).

Note that this also includes comments, entities and processing instructions. To filter them out, check if the tag property of the returned element is a string (i.e. not None and not a factory function), or pass the Element factory for the tag argument to receive only Elements.

If the optional tag argument is not None, the iterator returns only the elements that match the respective name and namespace.

The optional boolean argument ‘inclusive’ defaults to True and can be set to False to exclude the start element itself.

Note that the behaviour of this iterator is completely undefined if the tree it traverses is modified during iteration.

class lxml.etree.ElementNamespaceClassLookup(self, fallback=None)

Bases: FallbackElementClassLookup

Element class lookup scheme that searches the Element class in the Namespace registry.

Usage:

>>> lookup = ElementNamespaceClassLookup()
>>> ns_elements = lookup.get_namespace("http://schema.org/Movie")

>>> @ns_elements
... class movie(ElementBase):
...     "Element implementation for 'movie' tag (using class name) in schema namespace."

>>> @ns_elements("movie")
... class MovieElement(ElementBase):
...     "Element implementation for 'movie' tag (explicit tag name) in schema namespace."

get_namespace(self, ns_uri)

Retrieve the namespace object associated with the given URI. Pass None for the empty namespace.

Creates a new namespace object if it does not yet exist.

set_fallback(self, lookup): Sets the fallback scheme for this lookup method.

fallback

class lxml.etree.ElementTextIterator(self, element, tag=None, with_tail=True)

Bases: object

Iterates over the text content of a subtree.

You can pass the tag keyword argument to restrict text content to a specific tag name.

You can set the with_tail keyword argument to False to skip over tail text (e.g. if you know that it’s only whitespace from pretty-printing).

class lxml.etree.EntityBase

Bases: _Entity

All custom Entity classes must inherit from this one.

To create an XML Entity instance, use the Entity() factory.

Subclasses must not override __init__ or __new__ as it is absolutely undefined when these objects will be created or destroyed. All persistent state of Entities must be stored in the underlying XML. If you really need to initialize the object after creation, you can implement an _init(self) method that will be called after object creation.

_init(self): Called after object initialisation. Custom subclasses may override this if they recursively call _init() in the superclasses.

addnext(self, element)

Adds the element as a following sibling directly after this element.

This is normally used to set a processing instruction or comment after the root node of a document. Note that tail text is automatically discarded when adding at the root level.

addprevious(self, element)

Adds the element as a preceding sibling directly before this element.

This is normally used to set a processing instruction or comment before the root node of a document. Note that tail text is automatically discarded when adding at the root level.

append(self, value)

clear(self, keep_tail=False)

Resets an element. This function removes all subelements, clears all attributes and sets the text and tail properties to None.

Pass keep_tail=True to leave the tail text untouched.

cssselect(expr, *, translator='xml')

Run the CSS expression on this element and its children, returning a list of the results.

Equivalent to lxml.cssselect.CSSSelect(expr)(self) – note that pre-compiling the expression can provide a substantial speedup.

extend(self, elements): Extends the current children by the elements in the iterable.

find(self, path, namespaces=None)

Finds the first matching subelement, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

findall(self, path, namespaces=None)

Finds all matching subelements, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

findtext(self, path, default=None, namespaces=None)

Finds text for the first matching subelement, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

get(self, key, default=None)

getchildren(self)

Returns all direct children. The elements are returned in document order.

Deprecated:: Note that this method has been deprecated as of ElementTree 1.3 and lxml 2.0. New code should use list(element) or simply iterate over elements.

getiterator(self, tag=None, *tags)

Returns a sequence or iterator of all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags, see iter.

Deprecated:: Note that this method is deprecated as of ElementTree 1.3 and lxml 2.0. It returns an iterator in lxml, which diverges from the original ElementTree behaviour. If you want an efficient iterator, use the element.iter() method instead. You should only use this method in new code if you require backwards compatibility with older versions of lxml or ElementTree.

getnext(self): Returns the following sibling of this element or None.

getparent(self): Returns the parent of this element or None for the root element.

getprevious(self): Returns the preceding sibling of this element or None.

getroottree(self)

Return an ElementTree for the root node of the document that contains this element.

This is the same as following element.getparent() up the tree until it returns None (for the root element) and then build an ElementTree for the last parent that was returned.

index(self, child, start=None, stop=None)

Find the position of the child within the parent.

This method is not part of the original ElementTree API.

insert(self, index, value)

items(self)

iter(self, tag=None, *tags)

Iterate over all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags: pass "{ns}localname" as tag. Either or both of ns and localname can be * for a wildcard; ns can be empty for no namespace. "localname" is equivalent to "{}localname" (i.e. no namespace) but "*" is "{*}*" (any or no namespace), not "{}*".

You can also pass the Element, Comment, ProcessingInstruction and Entity factory functions to look only for the specific element type.

Passing multiple tags (or a sequence of tags) instead of a single tag will let the iterator return all elements matching any of these tags, in document order.

iterancestors(self, tag=None, *tags)

Iterate over the ancestors of this element (from parent to parent).

Can be restricted to find only elements with specific tags, see iter.

iterchildren(self, tag=None, *tags, reversed=False)

Iterate over the children of this element.

As opposed to using normal iteration on this element, the returned elements can be reversed with the ‘reversed’ keyword and restricted to find only elements with specific tags, see iter.

iterdescendants(self, tag=None, *tags)

Iterate over the descendants of this element in document order.

As opposed to el.iter(), this iterator does not yield the element itself. The returned elements can be restricted to find only elements with specific tags, see iter.

iterfind(self, path, namespaces=None)

Iterates over all matching subelements, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

itersiblings(self, tag=None, *tags, preceding=False)

Iterate over the following or preceding siblings of this element.

The direction is determined by the ‘preceding’ keyword which defaults to False, i.e. forward iteration over the following siblings. When True, the iterator yields the preceding siblings in reverse document order, i.e. starting right before the current element and going backwards.

Can be restricted to find only elements with specific tags, see iter.

itertext(self, tag=None, *tags, with_tail=True)

Iterates over the text content of a subtree.

You can pass tag names to restrict text content to specific elements, see iter.

You can set the with_tail keyword argument to False to skip over tail text.

keys(self)

makeelement(self, _tag, attrib=None, nsmap=None, **_extra): Creates a new element associated with the same document.

remove(self, element): Removes a matching subelement. Unlike the find methods, this method compares elements based on identity, not on tag value or contents.

replace(self, old_element, new_element): Replaces a subelement with the element passed as second argument.

set(self, key, value)

values(self)

xpath(self, _path, namespaces=None, extensions=None, smart_strings=True, **_variables): Evaluate an xpath expression using the element as context node.

attrib

base

The base URI of the Element (xml:base or HTML base URL). None if the base URI is unknown.

Note that the value depends on the URL of the document that holds the Element if there is no xml:base attribute on the Element or its ancestors.

Setting this property will set an xml:base attribute on the Element, regardless of the document type (XML or HTML).

name

nsmap

Namespace prefix->URI mapping known in the context of this Element. This includes all namespace declarations of the parents.

Note that changing the returned dict has no effect on the Element.

prefix: Namespace prefix or None.

sourceline: Original line number as found by the parser or None if unknown.

tag

tail: Text after this element’s end tag, but before the next sibling element’s start tag. This is either a string or the value None, if there was no text.

class lxml.etree.FallbackElementClassLookup(self, fallback=None)

Bases: ElementClassLookup

Superclass of Element class lookups with additional fallback.

set_fallback(self, lookup): Sets the fallback scheme for this lookup method.

fallback

class lxml.etree.HTMLParser(self, encoding=None, remove_blank_text=False, remove_comments=False, remove_pis=False, no_network=True, target=None, schema: XMLSchema = None, recover=True, compact=True, collect_ids=True, huge_tree=False)

Bases: _FeedParser

The HTML parser.

This parser allows reading HTML into a normal XML tree. By default, it can read broken (non well-formed) HTML, depending on the capabilities of libxml2. Use the ‘recover’ option to switch this off.

Available boolean keyword arguments:

recover - try hard to parse through broken HTML (default: True)
no_network - prevent network access for related files (default: True)
remove_blank_text - discard empty text nodes that are ignorable (i.e. not actual text content)
remove_comments - discard comments
remove_pis - discard processing instructions
compact - save memory for short text content (default: True)
default_doctype - add a default doctype even if it is not found in the HTML (default: True)
collect_ids - use a hash table of XML IDs for fast access (default: True)
huge_tree - disable security restrictions and support very deep trees
and very long text content (only affects libxml2 2.7+)

Other keyword arguments:

encoding - override the document encoding (note: libiconv encoding name)
target - a parser target object that will receive the parse events
schema - an XMLSchema to validate against

Note that you should avoid sharing parsers between threads for performance reasons.

close(self)

Terminates feeding data to this parser. This tells the parser to process any remaining data in the feed buffer, and then returns the root Element of the tree that was parsed.

This method must be called after passing the last chunk of data into the feed() method. It should only be called when using the feed parser interface, all other usage is undefined.

copy(self): Create a new parser with the same configuration.

feed(self, data)

Feeds data to the parser. The argument should be an 8-bit string buffer containing encoded data, although Unicode is supported as long as both string types are not mixed.

This is the main entry point to the consumer interface of a parser. The parser will parse as much of the XML stream as it can on each call. To finish parsing or to reset the parser, call the close() method. Both methods may raise ParseError if errors occur in the input data. If an error is raised, there is no longer a need to call close().

The feed parser interface is independent of the normal parser usage. You can use the same parser as a feed parser and in the parse() function concurrently.

makeelement(self, _tag, attrib=None, nsmap=None, **_extra): Creates a new element associated with this parser.

set_element_class_lookup(self, lookup=None)

Set a lookup scheme for element classes generated from this parser.

Reset it by passing None or nothing.

error_log: The error log of the last parser run.

feed_error_log

The error log of the last (or current) run of the feed parser.

Note that this is local to the feed parser and thus is different from what the error_log property returns.

resolvers: The custom resolver registry of this parser.

target

version: The version of the underlying XML parser.

class lxml.etree.HTMLPullParser(self, events=None, *, tag=None, base_url=None, **kwargs)

Bases: HTMLParser

HTML parser that collects parse events in an iterator.

The collected events are the same as for iterparse(), but the parser itself is non-blocking in the sense that it receives data chunks incrementally through its .feed() method, instead of reading them directly from a file(-like) object all by itself.

By default, it collects Element end events. To change that, pass any subset of the available events into the events argument: 'start', 'end', 'start-ns', 'end-ns', 'comment', 'pi'.

To support loading external dependencies relative to the input source, you can pass the base_url.

close(self)

Terminates feeding data to this parser. This tells the parser to process any remaining data in the feed buffer, and then returns the root Element of the tree that was parsed.

This method must be called after passing the last chunk of data into the feed() method. It should only be called when using the feed parser interface, all other usage is undefined.

copy(self): Create a new parser with the same configuration.

feed(self, data)

Feeds data to the parser. The argument should be an 8-bit string buffer containing encoded data, although Unicode is supported as long as both string types are not mixed.

This is the main entry point to the consumer interface of a parser. The parser will parse as much of the XML stream as it can on each call. To finish parsing or to reset the parser, call the close() method. Both methods may raise ParseError if errors occur in the input data.

makeelement(self, _tag, attrib=None, nsmap=None, **_extra): Creates a new element associated with this parser.

read_events()

set_element_class_lookup(self, lookup=None)

Set a lookup scheme for element classes generated from this parser.

Reset it by passing None or nothing.

error_log: The error log of the last parser run.

feed_error_log

The error log of the last (or current) run of the feed parser.

Note that this is local to the feed parser and thus is different from what the error_log property returns.

resolvers: The custom resolver registry of this parser.

target

version: The version of the underlying XML parser.

class lxml.etree.PIBase

Bases: _ProcessingInstruction

All custom Processing Instruction classes must inherit from this one.

To create an XML ProcessingInstruction instance, use the PI() factory.

Subclasses must not override __init__ or __new__ as it is absolutely undefined when these objects will be created or destroyed. All persistent state of PIs must be stored in the underlying XML. If you really need to initialize the object after creation, you can implement an _init(self) method that will be called after object creation.

_init(self): Called after object initialisation. Custom subclasses may override this if they recursively call _init() in the superclasses.

addnext(self, element)

Adds the element as a following sibling directly after this element.

This is normally used to set a processing instruction or comment after the root node of a document. Note that tail text is automatically discarded when adding at the root level.

addprevious(self, element)

Adds the element as a preceding sibling directly before this element.

This is normally used to set a processing instruction or comment before the root node of a document. Note that tail text is automatically discarded when adding at the root level.

append(self, value)

clear(self, keep_tail=False)

Resets an element. This function removes all subelements, clears all attributes and sets the text and tail properties to None.

Pass keep_tail=True to leave the tail text untouched.

cssselect(expr, *, translator='xml')

Run the CSS expression on this element and its children, returning a list of the results.

Equivalent to lxml.cssselect.CSSSelect(expr)(self) – note that pre-compiling the expression can provide a substantial speedup.

extend(self, elements): Extends the current children by the elements in the iterable.

find(self, path, namespaces=None)

Finds the first matching subelement, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

findall(self, path, namespaces=None)

Finds all matching subelements, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

findtext(self, path, default=None, namespaces=None)

Finds text for the first matching subelement, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

get(self, key, default=None)

Try to parse pseudo-attributes from the text content of the processing instruction, search for one with the given key as name and return its associated value.

Note that this is only a convenience method for the most common case that all text content is structured in attribute-like name-value pairs with properly quoted values. It is not guaranteed to work for all possible text content.

getchildren(self)

Returns all direct children. The elements are returned in document order.

Deprecated:: Note that this method has been deprecated as of ElementTree 1.3 and lxml 2.0. New code should use list(element) or simply iterate over elements.

getiterator(self, tag=None, *tags)

Returns a sequence or iterator of all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags, see iter.

Deprecated:: Note that this method is deprecated as of ElementTree 1.3 and lxml 2.0. It returns an iterator in lxml, which diverges from the original ElementTree behaviour. If you want an efficient iterator, use the element.iter() method instead. You should only use this method in new code if you require backwards compatibility with older versions of lxml or ElementTree.

getnext(self): Returns the following sibling of this element or None.

getparent(self): Returns the parent of this element or None for the root element.

getprevious(self): Returns the preceding sibling of this element or None.

getroottree(self)

Return an ElementTree for the root node of the document that contains this element.

This is the same as following element.getparent() up the tree until it returns None (for the root element) and then build an ElementTree for the last parent that was returned.

index(self, child, start=None, stop=None)

Find the position of the child within the parent.

This method is not part of the original ElementTree API.

insert(self, index, value)

items(self)

iter(self, tag=None, *tags)

Iterate over all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags: pass "{ns}localname" as tag. Either or both of ns and localname can be * for a wildcard; ns can be empty for no namespace. "localname" is equivalent to "{}localname" (i.e. no namespace) but "*" is "{*}*" (any or no namespace), not "{}*".

You can also pass the Element, Comment, ProcessingInstruction and Entity factory functions to look only for the specific element type.

Passing multiple tags (or a sequence of tags) instead of a single tag will let the iterator return all elements matching any of these tags, in document order.

iterancestors(self, tag=None, *tags)

Iterate over the ancestors of this element (from parent to parent).

Can be restricted to find only elements with specific tags, see iter.

iterchildren(self, tag=None, *tags, reversed=False)

Iterate over the children of this element.

As opposed to using normal iteration on this element, the returned elements can be reversed with the ‘reversed’ keyword and restricted to find only elements with specific tags, see iter.

iterdescendants(self, tag=None, *tags)

Iterate over the descendants of this element in document order.

As opposed to el.iter(), this iterator does not yield the element itself. The returned elements can be restricted to find only elements with specific tags, see iter.

iterfind(self, path, namespaces=None)

Iterates over all matching subelements, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

itersiblings(self, tag=None, *tags, preceding=False)

Iterate over the following or preceding siblings of this element.

The direction is determined by the ‘preceding’ keyword which defaults to False, i.e. forward iteration over the following siblings. When True, the iterator yields the preceding siblings in reverse document order, i.e. starting right before the current element and going backwards.

Can be restricted to find only elements with specific tags, see iter.

itertext(self, tag=None, *tags, with_tail=True)

Iterates over the text content of a subtree.

You can pass tag names to restrict text content to specific elements, see iter.

You can set the with_tail keyword argument to False to skip over tail text.

keys(self)

makeelement(self, _tag, attrib=None, nsmap=None, **_extra): Creates a new element associated with the same document.

remove(self, element): Removes a matching subelement. Unlike the find methods, this method compares elements based on identity, not on tag value or contents.

replace(self, old_element, new_element): Replaces a subelement with the element passed as second argument.

set(self, key, value)

values(self)

xpath(self, _path, namespaces=None, extensions=None, smart_strings=True, **_variables): Evaluate an xpath expression using the element as context node.

attrib: Returns a dict containing all pseudo-attributes that can be parsed from the text content of this processing instruction. Note that modifying the dict currently has no effect on the XML node, although this is not guaranteed to stay this way.

base

The base URI of the Element (xml:base or HTML base URL). None if the base URI is unknown.

Note that the value depends on the URL of the document that holds the Element if there is no xml:base attribute on the Element or its ancestors.

Setting this property will set an xml:base attribute on the Element, regardless of the document type (XML or HTML).

nsmap

Namespace prefix->URI mapping known in the context of this Element. This includes all namespace declarations of the parents.

Note that changing the returned dict has no effect on the Element.

prefix: Namespace prefix or None.

sourceline: Original line number as found by the parser or None if unknown.

tag

tail: Text after this element’s end tag, but before the next sibling element’s start tag. This is either a string or the value None, if there was no text.

target

text

class lxml.etree.ParserBasedElementClassLookup(self, fallback=None)

Bases: FallbackElementClassLookup

Element class lookup based on the XML parser.

set_fallback(self, lookup): Sets the fallback scheme for this lookup method.

fallback

class lxml.etree.PyErrorLog(self, logger_name=None, logger=None)

Bases: _BaseErrorLog

A global error log that connects to the Python stdlib logging package.

The constructor accepts an optional logger name or a readily instantiated logger instance.

If you want to change the mapping between libxml2’s ErrorLevels and Python logging levels, you can modify the level_map dictionary from a subclass.

The default mapping is:

ErrorLevels.WARNING = logging.WARNING
ErrorLevels.ERROR   = logging.ERROR
ErrorLevels.FATAL   = logging.CRITICAL

You can also override the method receive() that takes a LogEntry object and calls self.log(log_entry, format_string, arg1, arg2, ...) with appropriate data.

copy(): Dummy method that returns an empty error log.

log(self, log_entry, message, *args)

Called by the .receive() method to log a _LogEntry instance to the Python logging system. This handles the error level mapping.

In the default implementation, the message argument receives a complete log line, and there are no further args. To change the message format, it is best to override the .receive() method instead of this one.

receive(self, log_entry)

Receive a _LogEntry instance from the logging system. Calls the .log() method with appropriate parameters:

self.log(log_entry, repr(log_entry))

You can override this method to provide your own log output format.

last_error

level_map

class lxml.etree.PythonElementClassLookup(self, fallback=None)

Bases: FallbackElementClassLookup

Element class lookup based on a subclass method.

This class lookup scheme allows access to the entire XML tree in read-only mode. To use it, re-implement the lookup(self, doc, root) method in a subclass:

from lxml import etree, pyclasslookup

class MyElementClass(etree.ElementBase):
    honkey = True

class MyLookup(pyclasslookup.PythonElementClassLookup):
    def lookup(self, doc, root):
        if root.tag == "sometag":
            return MyElementClass
        else:
            for child in root:
                if child.tag == "someothertag":
                    return MyElementClass
        # delegate to default
        return None

If you return None from this method, the fallback will be called.

The first argument is the opaque document instance that contains the Element. The second argument is a lightweight Element proxy implementation that is only valid during the lookup. Do not try to keep a reference to it. Once the lookup is done, the proxy will be invalid.

Also, you cannot wrap such a read-only Element in an ElementTree, and you must take care not to keep a reference to them outside of the lookup() method.

Note that the API of the Element objects is not complete. It is purely read-only and does not support all features of the normal lxml.etree API (such as XPath, extended slicing or some iteration methods).

See https://lxml.de/element_classes.html

lookup(self, doc, element): Override this method to implement your own lookup scheme.

set_fallback(self, lookup): Sets the fallback scheme for this lookup method.

fallback

class lxml.etree.QName(text_or_uri_or_element, tag=None)

Bases: object

QName wrapper for qualified XML names.

Pass a tag name by itself or a namespace URI and a tag name to create a qualified name. Alternatively, pass an Element to extract its tag name. None as first argument is ignored in order to allow for generic 2-argument usage.

The text property holds the qualified name in {namespace}tagname notation. The namespace and localname properties hold the respective parts of the tag name.

You can pass QName objects wherever a tag name is expected. Also, setting Element text from a QName will resolve the namespace prefix on assignment and set a qualified text value. This is helpful in XML languages like SOAP or XML-Schema that use prefixed tag names in their text content.

localname

namespace

text

class lxml.etree.RelaxNG(self, etree=None, file=None)

Bases: _Validator

Turn a document into a Relax NG validator.

Either pass a schema as Element or ElementTree, or pass a file or filename through the file keyword argument.

_append_log_message(domain, type, level, line, message, filename)

_clear_error_log()

assertValid(self, etree): Raises DocumentInvalid if the document does not comply with the schema.

assert_(self, etree): Raises AssertionError if the document does not comply with the schema.

classmethod from_rnc_string(src, base_url=None)

Parse a RelaxNG schema in compact syntax from a text string

Requires the rnc2rng package to be installed.

Passing the source URL or file path of the source as ‘base_url’ will enable resolving resource references relative to the source.

validate(self, etree)

Validate the document using this schema.

Returns true if document is valid, false if not.

error_log: The log of validation errors and warnings.

class lxml.etree.RelaxNGErrorTypes

class lxml.etree.Resolver

Bases: object

This is the base class of all resolvers.

resolve(self, system_url, public_id, context)

Override this method to resolve an external source by system_url and public_id. The third argument is an opaque context object.

Return the result of one of the resolve_*() methods.

resolve_empty(self, context)

Return an empty input document.

Pass context as parameter.

resolve_file(self, f, context, base_url=None, close=True)

Return an open file-like object as input document.

Pass open file and context as parameters. You can pass the base URL or filename of the file through the base_url keyword argument. If the close flag is True (the default), the file will be closed after reading.

Note that using .resolve_filename() is more efficient, especially in threaded environments.

resolve_filename(self, filename, context)

Return the name of a parsable file as input document.

Pass filename and context as parameters. You can also pass a URL with an HTTP, FTP or file target.

resolve_string(self, string, context, base_url=None)

Return a parsable string as input document.

Pass data string and context as parameters. You can pass the source URL or filename through the base_url keyword argument.

class lxml.etree.Schematron(self, etree=None, file=None)

Bases: _Validator

A Schematron validator.

Pass a root Element or an ElementTree to turn it into a validator. Alternatively, pass a filename as keyword argument ‘file’ to parse from the file system.

Schematron is a less well known, but very powerful schema language. The main idea is to use the capabilities of XPath to put restrictions on the structure and the content of XML documents. Here is a simple example:

>>> schematron = Schematron(XML('''
... <schema xmlns="http://www.ascc.net/xml/schematron" >
...   <pattern name="id is the only permitted attribute name">
...     <rule context="*">
...       <report test="@*[not(name()='id')]">Attribute
...         <name path="@*[not(name()='id')]"/> is forbidden<name/>
...       </report>
...     </rule>
...   </pattern>
... </schema>
... '''))

>>> xml = XML('''
... <AAA name="aaa">
...   <BBB id="bbb"/>
...   <CCC color="ccc"/>
... </AAA>
... ''')

>>> schematron.validate(xml)
0

>>> xml = XML('''
... <AAA id="aaa">
...   <BBB id="bbb"/>
...   <CCC/>
... </AAA>
... ''')

>>> schematron.validate(xml)
1

Schematron was added to libxml2 in version 2.6.21. Before version 2.6.32, however, Schematron lacked support for error reporting other than to stderr. This version is therefore required to retrieve validation warnings and errors in lxml.

_append_log_message(domain, type, level, line, message, filename)

_clear_error_log()

assertValid(self, etree): Raises DocumentInvalid if the document does not comply with the schema.

assert_(self, etree): Raises AssertionError if the document does not comply with the schema.

validate(self, etree)

Validate the document using this schema.

Returns true if document is valid, false if not.

error_log: The log of validation errors and warnings.

class lxml.etree.SiblingsIterator(self, node, tag=None, preceding=False)

Bases: _ElementMatchIterator

Iterates over the siblings of an element.

You can pass the boolean keyword preceding to specify the direction.

class lxml.etree.TreeBuilder

Bases: _SaxParserTarget

TreeBuilder(self, element_factory=None, parser=None,: comment_factory=None, pi_factory=None, insert_comments=True, insert_pis=True)

Parser target that builds a tree from parse event callbacks.

The factory arguments can be used to influence the creation of elements, comments and processing instructions.

By default, comments and processing instructions are inserted into the tree, but they can be ignored by passing the respective flags.

The final tree is returned by the close() method.

close(self): Flushes the builder buffers, and returns the toplevel document element. Raises XMLSyntaxError on inconsistencies.

comment(self, comment): Creates a comment using the factory, appends it (unless disabled) and returns it.

data(self, data): Adds text to the current element. The value should be either an 8-bit string containing ASCII text, or a Unicode string.

end(self, tag): Closes the current element.

pi(self, target, data=None): Creates a processing instruction using the factory, appends it (unless disabled) and returns it.

start(self, tag, attrs, nsmap=None): Opens a new element.

class lxml.etree.XInclude(self)

Bases: object

XInclude processor.

Create an instance and call it on an Element to run XInclude processing.

error_log

class lxml.etree.XMLParser(self, encoding=None, attribute_defaults=False, dtd_validation=False, load_dtd=False, no_network=True, ns_clean=False, recover=False, schema: XMLSchema = None, huge_tree=False, remove_blank_text=False, resolve_entities=True, remove_comments=False, remove_pis=False, strip_cdata=True, collect_ids=True, target=None, compact=True)

Bases: _FeedParser

The XML parser.

Parsers can be supplied as additional argument to various parse functions of the lxml API. A default parser is always available and can be replaced by a call to the global function ‘set_default_parser’. New parsers can be created at any time without a major run-time overhead.

The keyword arguments in the constructor are mainly based on the libxml2 parser configuration. A DTD will also be loaded if DTD validation or attribute default values are requested (unless you additionally provide an XMLSchema from which the default attributes can be read).

Available boolean keyword arguments:

attribute_defaults - inject default attributes from DTD or XMLSchema
dtd_validation - validate against a DTD referenced by the document
load_dtd - use DTD for parsing
no_network - prevent network access for related files (default: True)
ns_clean - clean up redundant namespace declarations
recover - try hard to parse through broken XML
remove_blank_text - discard blank text nodes that appear ignorable
remove_comments - discard comments
remove_pis - discard processing instructions
strip_cdata - replace CDATA sections by normal text content (default: True)
compact - save memory for short text content (default: True)
collect_ids - use a hash table of XML IDs for fast access (default: True, always True with DTD validation)
huge_tree - disable security restrictions and support very deep trees
and very long text content (only affects libxml2 2.7+)

Other keyword arguments:

resolve_entities - replace entities by their text value: False for keeping the
entity references, True for resolving them, and ‘internal’ for resolving internal definitions only (no external file/URL access). The default used to be True and was changed to ‘internal’ in lxml 5.0.
encoding - override the document encoding (note: libiconv encoding name)
target - a parser target object that will receive the parse events
schema - an XMLSchema to validate against

Note that you should avoid sharing parsers between threads. While this is not harmful, it is more efficient to use separate parsers. This does not apply to the default parser.

close(self)

Terminates feeding data to this parser. This tells the parser to process any remaining data in the feed buffer, and then returns the root Element of the tree that was parsed.

This method must be called after passing the last chunk of data into the feed() method. It should only be called when using the feed parser interface, all other usage is undefined.

copy(self): Create a new parser with the same configuration.

feed(self, data)

Feeds data to the parser. The argument should be an 8-bit string buffer containing encoded data, although Unicode is supported as long as both string types are not mixed.

This is the main entry point to the consumer interface of a parser. The parser will parse as much of the XML stream as it can on each call. To finish parsing or to reset the parser, call the close() method. Both methods may raise ParseError if errors occur in the input data. If an error is raised, there is no longer a need to call close().

The feed parser interface is independent of the normal parser usage. You can use the same parser as a feed parser and in the parse() function concurrently.

makeelement(self, _tag, attrib=None, nsmap=None, **_extra): Creates a new element associated with this parser.

set_element_class_lookup(self, lookup=None)

Set a lookup scheme for element classes generated from this parser.

Reset it by passing None or nothing.

error_log: The error log of the last parser run.

feed_error_log

The error log of the last (or current) run of the feed parser.

Note that this is local to the feed parser and thus is different from what the error_log property returns.

resolvers: The custom resolver registry of this parser.

target

version: The version of the underlying XML parser.

class lxml.etree.XMLPullParser(self, events=None, *, tag=None, **kwargs)

Bases: XMLParser

XML parser that collects parse events in an iterator.

The collected events are the same as for iterparse(), but the parser itself is non-blocking in the sense that it receives data chunks incrementally through its .feed() method, instead of reading them directly from a file(-like) object all by itself.

By default, it collects Element end events. To change that, pass any subset of the available events into the events argument: 'start', 'end', 'start-ns', 'end-ns', 'comment', 'pi'.

To support loading external dependencies relative to the input source, you can pass the base_url.

close(self)

Terminates feeding data to this parser. This tells the parser to process any remaining data in the feed buffer, and then returns the root Element of the tree that was parsed.

This method must be called after passing the last chunk of data into the feed() method. It should only be called when using the feed parser interface, all other usage is undefined.

copy(self): Create a new parser with the same configuration.

feed(self, data)

Feeds data to the parser. The argument should be an 8-bit string buffer containing encoded data, although Unicode is supported as long as both string types are not mixed.

This is the main entry point to the consumer interface of a parser. The parser will parse as much of the XML stream as it can on each call.

makeelement(self, _tag, attrib=None, nsmap=None, **_extra): Creates a new element associated with this parser.

read_events()

set_element_class_lookup(self, lookup=None)

Set a lookup scheme for element classes generated from this parser.

Reset it by passing None or nothing.

error_log: The error log of the last parser run.

feed_error_log

The error log of the last (or current) run of the feed parser.

Note that this is local to the feed parser and thus is different from what the error_log property returns.

resolvers: The custom resolver registry of this parser.

target

version: The version of the underlying XML parser.

class lxml.etree.XMLSchema(self, etree=None, file=None)

Bases: _Validator

Turn a document into an XML Schema validator.

Either pass a schema as Element or ElementTree, or pass a file or filename through the file keyword argument.

Passing the attribute_defaults boolean option will make the schema insert default/fixed attributes into validated documents.

_append_log_message(domain, type, level, line, message, filename)

_clear_error_log()

assertValid(self, etree): Raises DocumentInvalid if the document does not comply with the schema.

assert_(self, etree): Raises AssertionError if the document does not comply with the schema.

validate(self, etree)

Validate the document using this schema.

Returns true if document is valid, false if not.

error_log: The log of validation errors and warnings.

lxml.etree.XMLTreeBuilder: alias of ETCompatXMLParser

class lxml.etree.XPath(self, path, namespaces=None, extensions=None, regexp=True, smart_strings=True)

Bases: _XPathEvaluatorBase

A compiled XPath expression that can be called on Elements and ElementTrees.

Besides the XPath expression, you can pass prefix-namespace mappings and extension functions to the constructor through the keyword arguments namespaces and extensions. EXSLT regular expression support can be disabled with the ‘regexp’ boolean keyword (defaults to True). Smart strings will be returned for string results unless you pass smart_strings=False.

error_log

path: The literal XPath expression.

class lxml.etree.XPathDocumentEvaluator(self, etree, namespaces=None, extensions=None, regexp=True, smart_strings=True)

Bases: XPathElementEvaluator

Create an XPath evaluator for an ElementTree.

Additional namespace declarations can be passed with the ‘namespace’ keyword argument. EXSLT regular expression support can be disabled with the ‘regexp’ boolean keyword (defaults to True). Smart strings will be returned for string results unless you pass smart_strings=False.

register_namespace(prefix, uri): Register a namespace with the XPath context.

register_namespaces(namespaces): Register a prefix -> uri dict.

error_log

class lxml.etree.XPathElementEvaluator(self, element, namespaces=None, extensions=None, regexp=True, smart_strings=True)

Bases: _XPathEvaluatorBase

Create an XPath evaluator for an element.

Absolute XPath expressions (starting with ‘/’) will be evaluated against the ElementTree as returned by getroottree().

Additional namespace declarations can be passed with the ‘namespace’ keyword argument. EXSLT regular expression support can be disabled with the ‘regexp’ boolean keyword (defaults to True). Smart strings will be returned for string results unless you pass smart_strings=False.

register_namespace(prefix, uri): Register a namespace with the XPath context.

register_namespaces(namespaces): Register a prefix -> uri dict.

error_log

class lxml.etree.XSLT(self, xslt_input, extensions=None, regexp=True, access_control=None)

Bases: object

Turn an XSL document into an XSLT object.

Calling this object on a tree or Element will execute the XSLT:

transform = etree.XSLT(xsl_tree)
result = transform(xml_tree)

Keyword arguments of the constructor:

extensions: a dict mapping (namespace, name) pairs to extension functions or extension elements
regexp: enable exslt regular expression support in XPath (default: True)
access_control: access restrictions for network or file system (see XSLTAccessControl)

Keyword arguments of the XSLT call:

profile_run: enable XSLT profiling and make the profile available as XML document in result.xslt_profile (default: False)

Other keyword arguments of the call are passed to the stylesheet as parameters.

static set_global_max_depth(max_depth)

The maximum traversal depth that the stylesheet engine will allow. This does not only count the template recursion depth but also takes the number of variables/parameters into account. The required setting for a run depends on both the stylesheet and the input data.

Example:

XSLT.set_global_max_depth(5000)

Note that this is currently a global, module-wide setting because libxslt does not support it at a per-stylesheet level.

static strparam(strval)

Mark an XSLT string parameter that requires quote escaping before passing it into the transformation. Use it like this:

result = transform(doc, some_strval = XSLT.strparam(
    '''it's "Monty Python's" ...'''))

Escaped string parameters can be reused without restriction.

tostring(self, result_tree)

Save result doc to string based on stylesheet output method.

Deprecated:: use str(result_tree) instead.

error_log: The log of errors and warnings of an XSLT execution.

class lxml.etree.XSLTAccessControl(self, read_file=True, write_file=True, create_dir=True, read_network=True, write_network=True)

Bases: object

Access control for XSLT: reading/writing files, directories and network I/O. Access to a type of resource is granted or denied by passing any of the following boolean keyword arguments. All of them default to True to allow access.

read_file
write_file
create_dir
read_network
write_network

For convenience, there is also a class member DENY_ALL that provides an XSLTAccessControl instance that is readily configured to deny everything, and a DENY_WRITE member that denies all write access but allows read access.

See XSLT.

DENY_ALL = XSLTAccessControl(create_dir=False, read_file=False, read_network=False, write_file=False, write_network=False)

DENY_WRITE = XSLTAccessControl(create_dir=False, read_file=True, read_network=True, write_file=False, write_network=False)

options: The access control configuration as a map of options.

class lxml.etree.XSLTExtension

Bases: object

Base class of an XSLT extension element.

apply_templates(self, context, node, output_parent=None, elements_only=False, remove_blank_text=False)

Call this method to retrieve the result of applying templates to an element.

The return value is a list of elements or text strings that were generated by the XSLT processor. If you pass elements_only=True, strings will be discarded from the result list. The option remove_blank_text=True will only discard strings that consist entirely of whitespace (e.g. formatting). These options do not apply to Elements, only to bare string results.

If you pass an Element as output_parent parameter, the result will instead be appended to the element (including attributes etc.) and the return value will be None. This is a safe way to generate content into the output document directly, without having to take care of special values like text or attributes. Note that the string discarding options will be ignored in this case.

execute(self, context, self_node, input_node, output_parent)

Execute this extension element.

Subclasses must override this method. They may append elements to the output_parent element here, or set its text content. To this end, the input_node provides read-only access to the current node in the input document, and the self_node points to the extension element in the stylesheet.

Note that the output_parent parameter may be None if there is no parent element in the current context (e.g. no content was added to the output tree yet).

process_children(self, context, output_parent=None, elements_only=False, remove_blank_text=False)

Call this method to process the XSLT content of the extension element itself.

The return value is a list of elements or text strings that were generated by the XSLT processor. If you pass elements_only=True, strings will be discarded from the result list. The option remove_blank_text=True will only discard strings that consist entirely of whitespace (e.g. formatting). These options do not apply to Elements, only to bare string results.

If you pass an Element as output_parent parameter, the result will instead be appended to the element (including attributes etc.) and the return value will be None. This is a safe way to generate content into the output document directly, without having to take care of special values like text or attributes. Note that the string discarding options will be ignored in this case.

class lxml.etree._Attrib

Bases: object

A dict-like proxy for the Element.attrib property.

clear()

get(key, default=None)

has_key(key)

items()

iteritems()

iterkeys()

itervalues()

keys()

pop(key, *default)

update(sequence_or_dict)

values()

class lxml.etree._BaseErrorLog

Bases: object

copy()

receive(entry)

last_error

class lxml.etree._Comment

Bases: __ContentOnlyElement

_init(self): Called after object initialisation. Custom subclasses may override this if they recursively call _init() in the superclasses.

addnext(self, element)

Adds the element as a following sibling directly after this element.

This is normally used to set a processing instruction or comment after the root node of a document. Note that tail text is automatically discarded when adding at the root level.

addprevious(self, element)

Adds the element as a preceding sibling directly before this element.

This is normally used to set a processing instruction or comment before the root node of a document. Note that tail text is automatically discarded when adding at the root level.

append(self, value)

clear(self, keep_tail=False)

Resets an element. This function removes all subelements, clears all attributes and sets the text and tail properties to None.

Pass keep_tail=True to leave the tail text untouched.

cssselect(expr, *, translator='xml')

Run the CSS expression on this element and its children, returning a list of the results.

Equivalent to lxml.cssselect.CSSSelect(expr)(self) – note that pre-compiling the expression can provide a substantial speedup.

extend(self, elements): Extends the current children by the elements in the iterable.

find(self, path, namespaces=None)

Finds the first matching subelement, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

findall(self, path, namespaces=None)

Finds all matching subelements, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

findtext(self, path, default=None, namespaces=None)

Finds text for the first matching subelement, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

get(self, key, default=None)

getchildren(self)

Returns all direct children. The elements are returned in document order.

Deprecated:: Note that this method has been deprecated as of ElementTree 1.3 and lxml 2.0. New code should use list(element) or simply iterate over elements.

getiterator(self, tag=None, *tags)

Returns a sequence or iterator of all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags, see iter.

Deprecated:: Note that this method is deprecated as of ElementTree 1.3 and lxml 2.0. It returns an iterator in lxml, which diverges from the original ElementTree behaviour. If you want an efficient iterator, use the element.iter() method instead. You should only use this method in new code if you require backwards compatibility with older versions of lxml or ElementTree.

getnext(self): Returns the following sibling of this element or None.

getparent(self): Returns the parent of this element or None for the root element.

getprevious(self): Returns the preceding sibling of this element or None.

getroottree(self)

Return an ElementTree for the root node of the document that contains this element.

This is the same as following element.getparent() up the tree until it returns None (for the root element) and then build an ElementTree for the last parent that was returned.

index(self, child, start=None, stop=None)

Find the position of the child within the parent.

This method is not part of the original ElementTree API.

insert(self, index, value)

items(self)

iter(self, tag=None, *tags)

Iterate over all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags: pass "{ns}localname" as tag. Either or both of ns and localname can be * for a wildcard; ns can be empty for no namespace. "localname" is equivalent to "{}localname" (i.e. no namespace) but "*" is "{*}*" (any or no namespace), not "{}*".

You can also pass the Element, Comment, ProcessingInstruction and Entity factory functions to look only for the specific element type.

Passing multiple tags (or a sequence of tags) instead of a single tag will let the iterator return all elements matching any of these tags, in document order.

iterancestors(self, tag=None, *tags)

Iterate over the ancestors of this element (from parent to parent).

Can be restricted to find only elements with specific tags, see iter.

iterchildren(self, tag=None, *tags, reversed=False)

Iterate over the children of this element.

As opposed to using normal iteration on this element, the returned elements can be reversed with the ‘reversed’ keyword and restricted to find only elements with specific tags, see iter.

iterdescendants(self, tag=None, *tags)

Iterate over the descendants of this element in document order.

As opposed to el.iter(), this iterator does not yield the element itself. The returned elements can be restricted to find only elements with specific tags, see iter.

iterfind(self, path, namespaces=None)

Iterates over all matching subelements, by tag name or path.

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

itersiblings(self, tag=None, *tags, preceding=False)

Iterate over the following or preceding siblings of this element.

The direction is determined by the ‘preceding’ keyword which defaults to False, i.e. forward iteration over the following siblings. When True, the iterator yields the preceding siblings in reverse document order, i.e. starting right before the current element and going backwards.

Can be restricted to find only elements with specific tags, see iter.

itertext(self, tag=None, *tags, with_tail=True)

Iterates over the text content of a subtree.

You can pass tag names to restrict text content to specific elements, see iter.

You can set the with_tail keyword argument to False to skip over tail text.

keys(self)

makeelement(self, _tag, attrib=None, nsmap=None, **_extra): Creates a new element associated with the same document.

This is normally used to set a processing instruction or comment before the root node of a document. Note that tail text is automatically discarded when adding at the root level.

append(self, element): Adds a subelement to the end of this element.

clear(self, keep_tail=False)

Resets an element. This function removes all subelements, clears all attributes and sets the text and tail properties to None.

Pass keep_tail=True to leave the tail text untouched.

cssselect(expr, *, translator='xml')

Run the CSS expression on this element and its children, returning a list of the results.

Equivalent to lxml.cssselect.CSSSelect(expr)(self) – note that pre-compiling the expression can provide a substantial speedup.

extend(self, elements): Extends the current children by the elements in the iterable.

getiterator(self, tag=None, *tags)

Returns a sequence or iterator of all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags, see iter.

Deprecated:: Note that this method is deprecated as of ElementTree 1.3 and lxml 2.0. It returns an iterator in lxml, which diverges from the original ElementTree behaviour.

Can be restricted to find only elements with specific tags: pass "{ns}localname" as tag. Either or both of ns and localname can be * for a wildcard; ns can be empty for no namespace. "localname" is equivalent to "{}localname" (i.e. no namespace) but "*" is "{*}*" (any or no namespace), not "{}*".

You can also pass the Element, Comment, ProcessingInstruction and Entity factory functions to look only for the specific element type.

Passing multiple tags (or a sequence of tags) instead of a single tag will let the iterator return all elements matching any of these tags, in document order.

iterancestors(self, tag=None, *tags)

Iterate over the ancestors of this element (from parent to parent).

Can be restricted to find only elements with specific tags, see iter.

iterchildren(self, tag=None, *tags, reversed=False)

Iterate over the following or preceding siblings of this element.

The direction is determined by the ‘preceding’ keyword which defaults to False, i.e. forward iteration over the following siblings. When True, the iterator yields the preceding siblings in reverse document order, i.e. starting right before the current element and going backwards.

Can be restricted to find only elements with specific tags, see iter.

Setting this property will set an xml:base attribute on the Element, regardless of the document type (XML or HTML).

nsmap

Namespace prefix->URI mapping known in the context of this Element. This includes all namespace declarations of the parents.

Note that changing the returned dict has no effect on the Element.

getelementpath(self, element)

Returns a structural, absolute ElementPath expression to find the element. This path can be used in the .find() method to look up the element, provided that the elements along the path and their list of immediate children were not modified in between.

ElementPath has the advantage over an XPath expression (as returned by the .getpath() method) that it does not require additional prefix declarations. It is always self-contained.

getiterator(self, *tags, tag=None)

Returns a sequence or iterator of all elements in document order (depth first pre-order), starting with the root element.

Can be restricted to find only elements with specific tags, see _Element.iter.

Deprecated:: Note that this method is deprecated as of ElementTree 1.3 and lxml 2.0. It returns an iterator in lxml, which diverges from the original ElementTree behaviour. If you want an efficient iterator, use the tree.iter() method instead. You should only use this method in new code if you require backwards compatibility with older versions of lxml or ElementTree.

getpath(self, element)

Returns a structural, absolute XPath expression to find the element.

For namespaced elements, the expression uses prefixes from the document, which therefore need to be provided in order to make any use of the expression in XPath.

Also see the method getelementpath(self, element), which returns a self-contained ElementPath expression.

getroot(self): Gets the root element for this tree.

iter(self, tag=None, *tags)

Write the tree to a filename, file or file-like object.

Defaults to ASCII encoding and writing a declaration as needed.

The keyword argument ‘method’ selects the output method: ‘xml’, ‘html’, ‘text’, ‘c14n’ or ‘c14n2’. Default is ‘xml’.

With method="c14n" (C14N version 1), the options exclusive, with_comments and inclusive_ns_prefixes request exclusive C14N, include comments, and list the inclusive prefixes respectively.

With method="c14n2" (C14N version 2), the with_comments and strip_text options control the output of comments and text space according to C14N 2.0.

Passing a boolean value to the standalone option will output an XML declaration with the corresponding standalone flag.

The doctype option allows passing in a plain string that will be serialised before the XML tree. Note that passing in non well-formed content here will make the XML output non well-formed. Also, an existing doctype in the document tree will not be removed when serialising an ElementTree instance.

The compression option enables GZip compression level 1-9.

The inclusive_ns_prefixes should be a list of namespace strings (i.e. [‘xs’, ‘xsi’]) that will be promoted to the top-level element during exclusive C14N serialisation. This parameter is ignored if exclusive mode=False.

If exclusive=True and no list is provided, a namespace will only be rendered if it is used by the immediate parent or one of its attributes and its prefix and values have not already been rendered by an ancestor of the namespace node’s parent element.

write_c14n(file, *, exclusive=False, with_comments=True, compression=0, inclusive_ns_prefixes=None)

write_c14n(self, file, exclusive=False, with_comments=True,: compression=0, inclusive_ns_prefixes=None)

C14N write of document. Always writes UTF-8.

The compression option enables GZip compression level 1-9.

The inclusive_ns_prefixes should be a list of namespace strings (i.e. [‘xs’, ‘xsi’]) that will be promoted to the top-level element during exclusive C14N serialisation. This parameter is ignored if exclusive mode=False.

If exclusive=True and no list is provided, a namespace will only be rendered if it is used by the immediate parent or one of its attributes and its prefix and values have not already been rendered by an ancestor of the namespace node’s parent element.

NOTE: This method is deprecated as of lxml 4.4 and will be removed in a future release. Use .write(f, method="c14n") instead.

xinclude(self)

Process the XInclude nodes in this document and include the referenced XML fragments.

Note that XInclude does not support custom resolvers in Python space due to restrictions of libxml2 <= 2.6.29.

xmlschema(self, xmlschema)

Validate this document using other document.

The xmlschema argument is a tree that should contain an XML Schema.

Returns True or False, depending on whether validation succeeded.

Note: If you are going to apply the same XML Schema against multiple documents, it is more efficient to use the XMLSchema class directly.

xpath(self, _path, namespaces=None, extensions=None, smart_strings=True, **_variables)

XPath evaluate in context of document.

namespaces is an optional dictionary with prefix to namespace URI mappings, used by XPath. extensions defines additional extension functions.

Returns a list (nodeset), or bool, float or string.

In case of a list result, return Element for element nodes, string for text and attribute values.

Note: if you are going to apply multiple XPath expressions against the same document, it is more efficient to use XPathEvaluator directly.

xslt(self, _xslt, extensions=None, access_control=None, **_kw)

Transform this document using other document.

xslt is a tree that should be XSLT keyword parameters are XSLT transformation parameters.

Returns the transformed tree.

Returns a sequence or iterator of all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags, see iter.

Deprecated:: Note that this method is deprecated as of ElementTree 1.3 and lxml 2.0. It returns an iterator in lxml, which diverges from the original ElementTree behaviour. If you want an efficient iterator, use the element.iter() method instead. You should only use this method in new code if you require backwards compatibility with older versions of lxml or ElementTree.

getprevious(self): Returns the preceding sibling of this element or None.

getroottree(self)

Return an ElementTree for the root node of the document that contains this element.

This is the same as following element.getparent() up the tree until it returns None (for the root element) and then build an ElementTree for the last parent that was returned.

index(self, child, start=None, stop=None)

Find the position of the child within the parent.

This method is not part of the original ElementTree API.

insert(self, index, value)

iter(self, tag=None, *tags)

Iterate over all elements in the subtree in document order (depth first pre-order), starting with this element.

Can be restricted to find only elements with specific tags: pass "{ns}localname" as tag. Either or both of ns and localname can be * for a wildcard; ns can be empty for no namespace. "localname" is equivalent to "{}localname" (i.e. no namespace) but "*" is "{*}*" (any or no namespace), not "{}*".

You can also pass the Element, Comment, ProcessingInstruction and Entity factory functions to look only for the specific element type.

Passing multiple tags (or a sequence of tags) instead of a single tag will let the iterator return all elements matching any of these tags, in document order.

Can be restricted to find only elements with specific tags, see iter.

iterchildren(self, tag=None, *tags, reversed=False)

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

itersiblings(self, tag=None, *tags, preceding=False)

Iterate over the following or preceding siblings of this element.

The direction is determined by the ‘preceding’ keyword which defaults to False, i.e. forward iteration over the following siblings. When True, the iterator yields the preceding siblings in reverse document order, i.e. starting right before the current element and going backwards.

Can be restricted to find only elements with specific tags, see iter.

itertext(self, tag=None, *tags, with_tail=True)

Iterates over the text content of a subtree.

You can pass tag names to restrict text content to specific elements, see iter.

You can set the with_tail keyword argument to False to skip over tail text.

copy(self): Create a new parser with the same configuration.

feed(self, data)

Feeds data to the parser. The argument should be an 8-bit string buffer containing encoded data, although Unicode is supported as long as both string types are not mixed.

This is the main entry point to the consumer interface of a parser. The parser will parse as much of the XML stream as it can on each call. To finish parsing or to reset the parser, call the close() method. Both methods may raise ParseError if errors occur in the input data. If an error is raised, there is no longer a need to call close().

The feed parser interface is independent of the normal parser usage. You can use the same parser as a feed parser and in the parse() function concurrently.

getroot(self): Gets the root element for this tree.

iter(self, tag=None, *tags)

Creates an iterator for the root element. The iterator loops over all elements in this tree, in document order. Note that siblings of the root element (comments or processing instructions) are not returned by the iterator.

Can be restricted to find only elements with specific tags, see _Element.iter.

iterfind(self, path, namespaces=None)

Iterates over all elements matching the ElementPath expression. Same as getroot().iterfind(path).

The optional namespaces argument accepts a prefix-to-namespace mapping that allows the usage of XPath prefixes in the path expression.

parse(self, source, parser=None, base_url=None): Updates self with the content of source and returns its root.

relaxng(self, relaxng)

Validate this document using other document.

The relaxng argument is a tree that should contain a Relax NG schema.

Returns True or False, depending on whether validation succeeded.

Note: if you are going to apply the same Relax NG schema against multiple documents, it is more efficient to use the RelaxNG class directly.
