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.
Sebastian

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).
