You might consider having constructor variants that use the
DefaultHTMLParserFeedback (by default ;-) so that users don't get
confused.

Sorry bout that - the web page hasnt been updated for a while. You will
need
to create a feedback object. If you dont need feedback from the parser,
use
the default one that we've provided in the com.kizna.html.util package.

Try this :

* Below is some sample code to parse Yahoo.com and print only the text
information. This scanning
* will run faster, as there are no scanners registered here.
HTMLParser parser =3D new HTMLParser("http://www.yahoo.com",new
DefaultHTMLParserFeedback());
// In this example, none of the scanners need to be registered
// as a string node is not a tag to be scanned for.
for (Enumeration e =3D parser.elements();e.hasMoreElements();) {
    HTMLNode node =3D (HTMLNode)e.nextElement();
    if (node instanceof HTMLStringNode) {
     HTMLStringNode stringNode =3D (HTMLStringNode)node;
     System.out.println(stringNode.getText());
    }
}

Let us know if you still face problems.

Regards,
Somik
