Perl Hash of arrays : comparison

[Sonika Sachdeva]

Hi,

I have Hash of array. I want to compare the array values within the hash.
How can it be done?

if ($eline =~ /$pattern/ ) {
                $eline =~ /(.*)\"(\w+)\s(.*)\?(.*)\"/ ; my $uniq=$1; my
$url=$4;
                chomp($uniq);chomp($url);
                my @var= ( split("&",$url) );
                foreach my $k (@var) {
                        @value = split("=",$k);
                        if ( $value[0] eq "package_guid" ) { push
@{$VAR{$uniq}},@value; }
                        if ( $value[0] eq "deployment_id" ) { push
@{$VAR{$uniq}},@value; }
                        }
                foreach my $x (keys %VAR) {
                        foreach my $y (keys %VAR) {
                                < Comparison code if 2 entries have same
pacakge_guid >                        }
                }
        }
