in reply to sort hash by value

sort an array instead :) step 1, select values you want to keep from hash.... stuff into an array, sort the array by any value

Re^2: sort hash by value (sort array)

    That would be easier except this is tied into a GUI and user values are going into array 0, old values are in array 1. I think you may have given me an answer anyhow though; flaten tag, type, and string into a 2d array then sort then use that output to order the hash output... 
    #head of code
my @array;
foreach my $tag (keys %licensehash) {
    foreach my $type (keys %{$licensehash{$tag}}) {
        push(@array, [$tag,$type,$licensehash{$tag}{$type}[3]]);
    }
}
@array = sort {$a->[2] cmp $b->[2]} @array;

#body of program (used more than once)
foreach my $order (@array) {
    print "$licensehash{@$order[0]}{@$order[1]}[3]";
}
