So what you need is an arbitrarily nested hash searcher? Yikes, those can get tricky. See ref, but I'd start out with (pseudo) code like the following:

sub find_value {
    my $hash_ref = shift;
    my $level;

    foreach my $key (keys %$hash_ref) {
        $level .= "$key\n";
        my $value = $hash_ref->{$key};
        if (ref($value) eq 'HASH') {
            $level .= find_value($value);
        } else {
            $level .= "\t$value\n";
        }
    }
    return $level;
}

That's untested, and it doesn't do anything that Data::Dumper doesn't do better... but it's a place to start.
