Hey monks,

Updating on some chatter yesterday in the CB: I've -again- a page I'm parsing. The parsing goes wel (with, I admit, a big ugly regex that probably could've been written much shorter), but now I want to assign a rank to each match, ie. the first match should get rank 1, the second match rank 2, ... the nth match should get rank n.

I came up with this: 
my $ranking_dgp = 0;

    do {
       my  $gene       = $1;
       my  $chromosone = $2;
       my  $score_dgp  = $3;
       $ranking_dgp = $ranking_dgp + 1;
        push @gene_score, [ $gene, $chromosone, $score_dgp, $ranking_d
+gp ];
    } while ( $text =~ m{gene\=(ENSG\d+).*?<TD>\s+(\d+|X|Y)\s+</TD>.*?
+<TD>.*?<TD>.*?<TD>.*?<TD>\s(\d.\d+)\s\<\/TD\>}gsm);

print Dumper @gene_score;

but it's one off: my first match gets rank 2. When I look at my output, I also see and understand why, but I can't think of a better way to do it. 

$VAR1 = [
          undef,
          undef,
          undef,
          '1'
        ];
$VAR2 = [
          'ENSG00000165659',
          '13',
          '0.738681',
          2
        ];
$VAR3 = [
          'ENSG00000184226',
          '13',
          '0.627447',
          3
        ];
