Function Details | [hide private]

### fragments_fromstring(html, no_leading_text=True, **kw) | source code
Parses several HTML elements, returning a list of elements. The first item in the list may be a string (though leading whitespace is removed). If no_leading_text is true, then it will be an error if there is leading text, and it will always be a list of only elements.

### fragment_fromstring(html, create_parent=True, **kw) | source code
Parses a single HTML element; it is an error if there is more than one element, or if anything but whitespace precedes or follows the element. If create_parent is true (or is a tag name) then a parent node will be created to encapsulate the HTML in a single element.

### fromstring(html, **kw) | source code
Parse the html, returning a single element/document. This tries to minimally parse the chunk of text, without knowing if it is a fragment or a document.

### parse(filename, parser=None, **kw) | source code
Parse a filename, URL, or file-like object into an HTML document. You may pass the keyword argument ``base_url='http://...'`` to set the base URL.

### submit_form(form, extra_values=None, open_http=None) | source code
Helper function to submit a form. Returns a file-like object, as from ``urllib.urlopen()``. This object also has a ``.geturl()`` function, which shows the URL if there were any redirects. You can use this like:
       >>> form = doc.forms[0]
       >>> form.inputs['foo'].value = 'bar' # etc
       >>> response = form.submit()
       >>> doc = parse(response)
       >>> doc.make_links_absolute(response.geturl())
To change the HTTP requester, pass a function as ``open_http`` keyword argument that opens the URL for you. The function must have the following signature:
       open_http(method, URL, values)
The action is one of 'GET' or 'POST', the URL is the target URL as a string, and the values are a sequence of ``(name, value)`` tuples with the form data.

### tostring(doc, pretty_print=True, include_meta_content_type=True, encoding=None) | source code
return HTML string representation of the document given note: if include_meta_content_type is true this will create a meta http-equiv="Content" tag in the head; regardless of the value of include_meta_content_type any existing meta http-equiv="Content" tag will be removed
