Dear Monks,

I'm new to Perl and was trying to extract the contents of a specific tag from my VLC webserver xml status page. Here's an example of the XML (I removed a couple of tags in the sections I'm not interested in to keep things shorter:

<root>
  <fullscreen>0</fullscreen>
  <audiodelay>0</audiodelay>
  <apiversion>3</apiversion>
  <time>1</time>
  <volume>256</volume>
  [...]
  <information>
    <category name="meta">
      <info name="title">CINEMIX</info>
      <info name="filename">CINEMIX</info>
      <info name="genre">Soundtracks Classical New Age</info>
      <info name="now_playing">John Williams-Losing E.T.-E.T. The Extr
+a-Terrestrial: 20th Anniversary</info>
    </category>
    <category name="Stream 0">
      <info name="Bitrate">192 kb/s</info>
      [...]
    </category>
  </information>
  <stats>
    <lostabuffers>2</lostabuffers>
    [...]
  </stats>
</root>

What I'm interested in is just the contents of the <info name="now_playing"> tag which contains artist, title and album.

I already have some code that does return all the <info> tags but I'm not sure how to specifically return just the "now_playing" tag content.

This is the code I managed to hack together so far using parts of code I found in the monastry:

#!/usr/bin/perl
 
use strict;
use XML::Rules;
use LWP::Simple;

my $streaminfo = get("http://127.0.0.1:8080/requests/status.xml"); 
  
my $parser = XML::Rules->new(
    stripspaces => 7,
    rules => {
        info => sub {
            print "$_[1]->{_content}\n";
            return;
        },
    }
);

I haven't been able to figure out how to filter the results to just the portion I'm interested to. I did look at the XML::Parser docs on cpan.org and have the feeling it's in there, especially the home / office phone example that's touched on in the synopsis, but I can't translate that into any working code.

Thanks for any assistance you can offer.
