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

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).
