Instance Methods | [hide private]

_label__get(self) Get or set any <label> element associated with this element. | 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. | source code

### 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.
