That's right! At least not in the while loop.

The value is changed in the start_document_handler (true) and 
end_document_handler (false). The loop is just to ensure the parser is not 
parsing.

But possibly I got confused, because I was handling with the ithread module 
and with locking and semaphores the last days!? :)

..
$p->parse;
my %links = $p->getHyperlinks;
..

Is there a chance that the calling program calls $p->getHyperlinks while the 
parser is still parsing the page? Or isn't it that the $p->getHyperlinks is 
called after the $p->parse returned (though without a value).

I am sorry if I am confusing someone.
