Interesting, when I built http://cQuery.com http://cQuery.com (Content Query Engine), I investigated a number of options html parsing and content extraction options. I had played with Rhino and John Resigs env.js (http://ejohn.org/blog/bringing-the-browser-to-the-server/ http://ejohn.org/blog/bringing-the-browser-to-the-server/) to run jQuery server-side. For portability, performance and flexability I finally settled for writing my own HTML parser and CSS selection engine from scratch.
