No, I think that s/he means that s/he wants to compare each of the values in the arrays pointed to (via array refs) by the corresponding keys in each hash. What I can't tell is if s/he expects the items to be in the same order in each hash or not.

If so, the most straight-forward way to do it would be something like: 

my @Non_Matching_Keys;
foreach $key (keys %HoL_compare_pub) {
    my @orig_a = @{$HoL_pub{$key)};
    my @comp_a = @{%HoL_compare_pub{$key}};
    foreach(0 .. @orig_a) {
        if($orig_a[$_] ne $comp_a[$_]) {
            push @Non_Matching_Keys, $key;
        }
    }
}

Note that that is totaly untested. Also, if the order of the two arrays are different, it won't work. Maybe running a sort() on them both first would work?

Update: Nevermind... I think I got confused by the "Hash of Arrays" part (and I was in a hurry to leave work ;-)... Looks like Tuna just wanted to see if a router (hash element) existed in one hash and not the other, just like dfog and dkubb said. =)
