( [id://3333]=superdoc: print w/replies, xml ) Need Help??

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; }

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 } }

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

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
