source code
 
_label__set(self, label) source code
 
_label__del(self) source code
 
drop_tree(self)
Removes this element from the tree, including its children and text. The tail text is joined to the previous element or parent.
source code
 
drop_tag(self)
Remove the tag, but not its children or text. The children and text are merged into the parent.
source code
 
find_rel_links(self, rel)
Find any links like <a rel="{rel}">...</a>; returns a list of elements.
source code
 
find_class(self, class_name)
Find any elements with the given class name.
source code
 
get_element_by_id(self, id, *default)
Get the first element in a document with the given id. If none is found, return the default argument if provided or raise KeyError otherwise.
source code
 
text_content(self)
Return the text content of the tag (and the text in any children).
source code
 
cssselect(self, expr)
Run the CSS expression on this element and its children, returning a list of the results.
source code
 
make_links_absolute(self, base_url=None, resolve_base_href=True)
Make all links in the document absolute, given the base_url for the document (the full URL where the document came from), or if no base_url is given, then the .base_url of the document.
source code
 
resolve_base_href(self)
Find any <base href> tag in the document, and apply its values to all links found in the document. Also remove the tag once it has been applied.
source code
 
iterlinks(self)
Yield (element, attribute, link, pos), where attribute may be None (indicating the link is in the text). pos is the position where the link occurs; often 0, but sometimes something else in the case of links in stylesheets or style tags.
source code
 
rewrite_links(self, link_repl_func, resolve_base_href=True, base_href=None)
Rewrite all the links in the document. For each link link_repl_func(link) will be called, and the return value will replace the old link.

Method Details [hide private]

drop_tag(self)

source code 

Remove the tag, but not its children or text. The children and text are merged into the parent.

Example:

>>> h = fragment_fromstring('<div>Hello <b>World!</b></div>')
>>> h.find('.//b').drop_tag()
>>> print(tostring(h, encoding=unicode))
<div>Hello World!</div>

get_element_by_id(self, id, *default)

source code 

Get the first element in a document with the given id. If none is found, return the default argument if provided or raise KeyError otherwise.

Note that there can be more than one element with the same id, and this isn't uncommon in HTML documents found in the wild. Browsers return only the first match, and this function does the same.

cssselect(self, expr)

source code 

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.

make_links_absolute(self, base_url=None, resolve_base_href=True)

source code 

Make all links in the document absolute, given the base_url for the document (the full URL where the document came from), or if no base_url is given, then the .base_url of the document.

If resolve_base_href is true, then any <base href> tags in the document are used and removed from the document. If it is false then any such tag is ignored.

iterlinks(self)

source code 

Yield (element, attribute, link, pos), where attribute may be None (indicating the link is in the text). pos is the position where the link occurs; often 0, but sometimes something else in the case of links in stylesheets or style tags.

Note: <base href> is not taken into account in any way. The link you get is exactly the link in the document.

rewrite_links(self, link_repl_func, resolve_base_href=True, base_href=None)

source code 

Rewrite all the links in the document. For each link link_repl_func(link) will be called, and the return value will replace the old link.

Note that links may not be absolute (unless you first called make_links_absolute()), and may be internal (e.g., '#anchor'). They can also be values like 'mailto:email' or 'javascript:expr'.

If you give base_href then all links passed to link_repl_func() will take that into account.

If the link_repl_func returns None, the attribute or tag text will be removed completely.
