Usage

Simple usage follows this pattern:

import html5libwith open("mydocument.html", "rb") as f: document = html5lib.parse(f)

or:

import html5libdocument = html5lib.parse("<p>Hello World!")

By default, the document will be an xml.etree element instance. Whenever possible, html5lib chooses the accelerated ElementTree implementation (i.e. xml.etree.cElementTree on Python 2.x).

Two other tree types are supported: xml.dom.minidom and lxml.etree. To use an alternative format, specify the name of a treebuilder:

import html5libwith open("mydocument.html", "rb") as f: lxml_etree_document = html5lib.parse(f, treebuilder="lxml")

When using with urllib2 (Python 2), the charset from HTTP should be pass into html5lib as follows:

from contextlib import closingfrom urllib2 import urlopenimport html5libwith closing(urlopen("http://example.com/")) as f: document = html5lib.parse(f, transport_encoding=f.info().getparam("charset"))

When using with urllib.request (Python 3), the charset from HTTP should be pass into html5lib as follows:

from urllib.request import urlopenimport html5libwith urlopen("http://example.com/") as f: document = html5lib.parse(f, transport_encoding=f.info().get_content_charset())

To have more control over the parser, create a parser object explicitly. For instance, to make the parser raise exceptions on parse errors, use:

import html5libwith open("mydocument.html", "rb") as f: parser = html5lib.HTMLParser(strict=True) document = parser.parse(f)

When you’re instantiating parser objects explicitly, pass a treebuilder class as the tree keyword argument to use an alternative document format:

import html5libparser = html5lib.HTMLParser(tree=html5lib.getTreeBuilder("dom"))minidom_document = parser.parse("<p>Hello World!")
