Hi Perlers, I am still learning XML::Twig and have a question. I have a couple of event handlers set up thusly, parsing a list of filenames stored in @files:

foreach my $file (@files){
# set up the XML parser:
 my $twig= XML::Twig->new( 
  twig_handlers => { topicref => \&topicref_processing,
               xref => \&topicref_processing },
 );
 $twig->parsefile($file);
 $twig->purge;
}

[download]

And I have the handler set up something like this:

sub topicref_processing {
  my($twig, $topicref) = @_;
  my($atts) = $topicref->atts();
  if($$atts{'keyref'}){
   ### associate this keyref with $file
  }
}

[download]

What I want to do is, if the handler finds a keyref attribute in the xref or topicref element, store that in a hash with the $file name as the key, something like $keyrefs{$file}{$$atts{'keyref'}} = 'keyref'.

What I can't figure out is, how to pass the name in $file to the event handler, or conversely, how to associate the found attribute back to the $file. I'm probably missing something obvious, but can't puzzle it out.

Any suggestions would be greatly appreciated.

Scott
