Re: [Htmlparser-developer] Automatic debug output

[Somik R. <so...@ya...>]

Sorry, I just saw your other mail again with the
output. I see the problem -

You must be calling the parse method in
HTMLParser.java. That is only a demo. As mentioned in
the docs, you should be doing something like :

(for HTMLEnumeration e =
parser.elements();e.hasMoreNodes();) {
   HTMLNode node = e.nextHTMLNode();
   // create summary here
}

The call to parse has the printing stuff which prints
all the details of the nodes (calling node.print()).

If this does not help, can you post your complete
parsing program ?

Regards,
Somik
