Some extra notes about your code: while (my ($keys, $values) = each %nums) {is probably a little more readable than while ((my $keys, my $values) = each (%nums)) {and you could prefer also to use open my $file, 'formal.xml'; instead: my $file;open $file, 'formal.xml');and print "num: $number\n"; instead: print( "num: $number\n" );
