I'd choose another way and use one of myriad Config::* CPAN modules. For example, with Config::Tiny you can do something similar to (after removing everything before the first section in your data file):

use warnings;
use strict;

use Config::Tiny;
my $cfg = Config::Tiny->read('test.txt') or die "Couldn't read file: $
+Config::Tiny::errstr";

for my $sect (values %$cfg) {
    my ($name, $version, $publisher) = map { $sect->{$_} } qw("Display
+Name" "DisplayVersion" "Publisher");
    print "Name: $name\nVersion: $version\nPublisher: $publisher\n";  
+  
}
