For detailed information about HTMLParser, the project is // hosted on sourceforge at http://htmlparser.sourceforge.net/. // // HTMLParser was originally created by Somik Raha in 2000. Since then // a healthy community of users has formed and helped refine the // design so that it is able to tackle the difficult task of parsing // dirty HTML.
