Re: extract tag content from VLC webserver via XML::Rules

[vagabonding electron]

Keeping your code as is your could just change this part:

my $parser = XML::Rules->new(
    stripspaces => 7,
    rules => {
        info => sub {
            print "$_[1]->{_content}\n" 
            if $_[1]->{name} eq 'now_playing'; # <-
            return;
        },
    }
);
$parser->parse( $xml);

which prints for me in your example:

John Williams-Losing E.T.-E.T. The Extra-Terrestrial: 20th Anniversary

Sweet, that's exactly what I was looking for!

Thanks for the regex suggestions as well. I was actually trying the regex route before but it's something I haven't much luck with wrapping my head around so far.

Love the super fast replies here. You guys are great.

Okay, I'm stuck again. I can print the now_playing content just fine, but that's not really my intention. I would like to use the data further down the line, but can't seem to get it out of the XML-Rules parser section.

I tried to populate a string called $nowplaying with it but outside of the parser section, the string prints just empty. Obviously, the print is again just temporary so I can see that it works before I continue.

How do I get the string contents outside of the parser section? Here's what I have:

my $nowplaying = "";

my $parser = XML::Rules->new(
    stripspaces => 7,
    rules => {
        info => sub {
            $nowplaying = $_[1]->{_content} 
            if $_[1]->{name} eq 'now_playing';
            return ;
        }
    }
);
$parser->parse($streaminfo);

print $nowplaying;

I'm sure it's again something real simple I'm missing here.

Just change the line

$nowplaying = $_[1]->{_content}

to

$nowplaying .= $_[1]->{_content}

You just missed the contatenation sign. :-)

Update: Another way could be to populate a data structure with this content, e.g. push @array,$_[1]->{_content} if ... where @array is declared outside the parser.

Update 2:After some thoughts: in fact your version works for me in the presented example too. However I reckon that you have more than one xml in your real script so that the content is lost if you have <info name="now_playing"/>somewhere later (though you should get a warning "Use of uninitialized value" - both in original and contatenation versions (in your OP you have not "use warnings" on).
