attibuts like this:
<font face="Arial" size="2"> the text to extract </font>

This kind of filtering can also be done by setting up the
'report_tags' attribute of the parser itself. That way of doing it is
much more efficient as it reduce the number of callbacks invoked
dramatically.

$parser->report_tags($want{tag});

Ah, yes. Thanks! In addition to the efficiency argument, I think it
improves the readablility of both start_h and end_h too.

Thanks again,
