Thought someone else might benefit from this.</p>

Revision 6. </p> <p>This is a state machine template. It can be used as a state machine, or a state machine tester. There is very little setup required and all the states are added based on the state docstring. I made this after a friend came to me asking how I'd implement one, complaining that he couldn't find a nice example. I hope this helps.</p>

Revision 2. </p> <p>Extensions of html.parser.HTMLParser().</p> <p>PrettyHTMLParser() does not splits data into chuncks by HTML entities. StatedHTMLParser() can have many state-dependent handlers which helps parsing HTML pages alot.</p>
