What is Hubbub?

Hubbub is an HTML5 compliant parsing library, written in C. It was developed as part of the NetSurf project and is available for use by other software under the MIT licence.

The HTML5 specification defines a parsing algorithm, based on the behaviour of mainstream browsers, which provides instructions for how to parse all markup, both valid and invalid. As a result, Hubbub parses web content well.

If you are looking for an HTML5 parser in Python or Ruby, you may wish to look at html5lib.
