Well I wrote the following:

private class BlankHTMLParserFeedback
implements HTMLParserFeedback
{
public void info(String message)
{
//System.out.println("INFO: " + message);
}

public void warning(String message)
{
//System.out.println("WARNING: " + message);
}

public void error(String message, HTMLParserException e)
{
//System.out.println("ERROR: " + message);
e.printStackTrace();
}
}



/**
* parse the page
*/
public final void parse()
throws Exception
{
if (o_parser==null)
o_parser = new HTMLParser(o_url, new BlankHTMLParserFeedback());

o_parser.addScanner(new HTMLMetaTagScanner("-t"));
o_parser.addScanner(new HTMLLinkScanner("-l"));
o_parser.addScanner(new HTMLTitleScanner("-a"));
parseURLForData();
o_summary = createSummary();
}

However I still seem to be getting the same debug output. Can you see
what I am doing wrong?

Have you considered using log4j? With log4j you have a log4j properties
file and you can specify the debug level on a class by class basis
within the properties file, and debug output can be formatted to give
you useful info such as the line number of the code where the debug
statement is.

Thanks in advance.

p.s. is there some operation for picking up HTML comments using the
HTMLParser (<!-- a comment -->) or are they automatically ignored?

Hi Sam,
  Can you post the debug output that you see ? Also,
if you can provide the url you are parsing, we can
attempt to duplicate this.
  Unfortunately my IDE crashed yesterday after I did a
Windows update, so I might take a day or two to get
back to programming from home.

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 ?
