Need help parsing html into JDK1.4.2's HTML DOM

I am writing an app that culls information from a website such as forms or pertinent information.  I need to grab the html, parse it into a tree structure such as JDK1.4's HTMLDocument or my own, have the app generate a gui off the model, gather user input, update the model, and submit the results back through the website.  I have looked into using regular expressions to parse the site, but am finding it to be too complex, not the parsing part if I know what I'm looking for, but in looping through the nested tables and mapping the inputs to java components.  I learned recently of the org.w3c.dom.html packages in jdk1.4.2, but it does not support the full dom2 specification which seems to be what I am looking for.  On top of that, I can't figure out how to parse the html into the htmDOM, let alone how to update the model with user input and submit the results.  I don't have any guarantees that the html is well formed, and the parsing must be pretty fast.

Any help/examples would be greatly appreciated. Thanks.

The webservices site is really great, but as what I'm working on will eventually go into a classified arena, I can't utilize anything web-based or 3rd Party.  I really need to get ahold of some open source code or use native api's to convert poor formed html to well formed xml, or use a native java parser to parse potentially poor formatted html directly.

I thought you couldn't use 3rd-party apis? What you've just described is a perfect description of what lies at the link i posted!
