Module etree

Build a dictionary of extension functions from the functions defined in a module or the methods of an object.

As second argument, you can pass an additional mapping of attribute names to XPath function names, or a list of function names that should be taken.

The ns keyword argument accepts a namespace URI for the XPath functions.

Retrieve the function namespace object associated with the given URI.

Creates a new one if it does not yet exist. A function namespace can only be used to register extension functions.

Parses an HTML document from a string constant. This function can be used to embed "HTML literals" in Python code.

To override the parser with a different HTMLParser you can pass it to the parser keyword argument.

The base_url keyword argument allows to set the original base URL of the document to support relative Paths when looking up external entities (DTD, XInclude, ...).

Parses an XML document from a string constant. This function can be used to embed "XML literals" in Python code, like in

>>> root = etree.XML("<root><test/></root>")

To override the parser with a different XMLParser you can pass it to the parser keyword argument.

The base_url keyword argument allows to set the original base URL of the document to support relative Paths when looking up external entities (DTD, XInclude, ...).

Parse the text and return a tuple (root node, ID dictionary). The root node is the same as returned by the XML() function. The dictionary contains string-element pairs. The dictionary keys are the values of ID attributes as defined by the DTD. The elements referenced by the ID are stored as dictionary values.

Note that you must not modify the XML tree if you use the ID dictionary. The results are undefined.

Creates an XPath evaluator for an ElementTree or an Element.

The resulting object can be called with an XPath expression as argument and XPath variables provided as keyword arguments.

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).

Parses an XML document from a string.

To override the default parser with a different parser you can pass it to the parser keyword argument.

The base_url keyword argument allows to set the original base URL of the document to support relative Paths when looking up external entities (DTD, XInclude, ...).

Parses an XML document from a sequence of strings.

To override the default parser with a different parser you can pass it to the parser keyword argument.

Return an ElementTree object loaded with source elements. If no parser is provided as second argument, the default parser is used.

The base_url keyword allows setting a URL for the document when parsing from a file-like object. This is needed when looking up external entities (DTD, XInclude, ...) with relative paths.

Parses the source into a tuple containing an ElementTree object and an ID dictionary. If no parser is provided as second argument, the default parser is used.

Note that you must not modify the XML tree if you use the ID dictionary. The results are undefined.

Set a default parser for the current thread. This parser is used globally whenever no parser is supplied to the various parse functions of the lxml API. If this function is called without a parser (or if it is None), the default parser is reset to the original configuration.

Note that the pre-installed default parser is not thread-safe. Avoid the default parser in multi-threaded environments. You can create a separate parser for each thread explicitly or use a parser pool.

Serialize an element to an encoded string representation of its XML tree.

Defaults to ASCII encoding without XML declaration. This behaviour can be configured with the keyword arguments 'encoding' (string) and 'xml_declaration' (bool). Note that changing the encoding to a non UTF-8 compatible encoding will enable a declaration by default.

You can also serialise to a Unicode string without declaration by passing the unicode function as encoding.

The keyword argument 'pretty_print' (bool) enables formatted XML.

The keyword argument 'method' selects the output method: 'xml', 'html' or plain 'text'.

You can prevent the tail text of the element from being serialised by passing the boolean with_tail option. This has no impact on the tail text of children, which will always be serialised.

Serialize an element to an encoded string representation of its XML tree, stored in a list of partial strings.

This is purely for ElementTree 1.3 compatibility. The result is a single string wrapped in a list.

Serialize an element to the Python unicode representation of its XML tree.

Note that the result does not carry an XML encoding declaration and is therefore not necessarily suited for serialization to byte streams without further treatment.

The boolean keyword argument 'pretty_print' enables formatted XML.

The keyword argument 'method' selects the output method: 'xml', 'html' or plain 'text'.

You can prevent the tail text of the element from being serialised by passing the boolean with_tail option. This has no impact on the tail text of children, which will always be serialised.

Replace the global error log by an etree.PyErrorLog that uses the standard Python logging package.

Note that this disables access to the global error log from exceptions. Parsers, XSLT etc. will continue to provide their normal local error log.
