[Htmlparser-user] Trouble overriding textnodes using setTextPrototype

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

// This code doesn't compile.  It complains "The constructor TextNode() is
undefined".   I got this in the documentation and thought it was a way to
override textnodes?
// My goal is to override TextNode so that I can process text and turn
http://link.com  into a real link  <a href="link.com">link.com</a>
// Any ideas?
