Hello,

I am a bit stuck here in finding a way how to do this. I'm trying to match some value in some text to get a number <gid=1234>. I want to replace this tag with <img src="PATH/TO/$id"> where the $id will be the number I matched eg. 1234.

Matching and fetching the id is no problem, but trying to replace the correct entry gives me a hassle. Especially when there are more entries in one line.

Some example code: 

use strict;

while (<DATA>) {
        my $line = $_;
        print $. . " " . $line;

        my @matches = /<gid=(\d+)>/g;

        foreach (@matches) {
                print "MATCH:: $_\n";
                $line =~ s/<gid=$1>/<img src="PATH\/TO\/$1>/
        }
        print "NEW" . $line;

}

__DATA__
<gid=3035>Wij zijn hier aan het moven. We gaan nog meer moven. <gid=30
+36>
Waarom wij dit doen weet ik ook niet. Maar we zullen het snel weten. <
+gid=3037>

<gid=3037>we testen dit zo.
