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: .. code-block:: python import html5lib with 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: .. code-block:: python from contextlib import closing from urllib2 import urlopen import html5lib with 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: .. code-block:: python from urllib.request import urlopen import html5lib with 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: .. code-block:: python import html5lib with 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: .. code-block:: python import html5lib parser = html5lib.HTMLParser(tree=html5lib.getTreeBuilder("dom")) minidom_document = parser.parse("

Hello World!") More documentation is available at https://html5lib.readthedocs.io/. Installation ------------ html5lib works on CPython 2.7+, CPython 3.5+ and PyPy. To install: .. code-block:: bash $ pip install html5lib The goal is to support a (non-strict) superset of the versions that [pip supports ]. Optional Dependencies
