HTML parser designed to follow the WHATWG HTML5 specification. The parser is designed to handle all flavours of HTML and parses invalid documents using well-defined error handling rules compatible with the behaviour of major desktop web browsers. Output is to a tree structure; the current release supports output to ElementTree (including cElementTree and lxml.etree), minidom, and a custom simpletree format. html5lib also includes a HTML sanitizer, "treewalkers" for converting various tree formats into streams and filters and serializers to operate on those streams.
