Hello monks,

This is Pingu, away from his usual machine and he's forgotten his password.

I'm bumbling around with Text::xSV, currently writing a new package to provide webpage based searching of xSV files. I've got my output from xSV as a hash of arrays, and I want to sort it by one of the array values. I have: 

...
    my $csv = Text::xSV->new();
    my %results;
    my $count;
    
    $csv->bind_header();
    while ($csv->get_row()) {
        @row =$csv->extract(@headers);
        $results{$count++} = [ @row ] unless ($notfound);
    }
    $self->{results} = \%results;

...
    my $results = $self{results};
    
    foreach (sort { return $$results{$a}[0] <=> $$results{$b}[0]; } ke
+ys %$results) {
        for (my $i=0; $i<@$headers; $i++) {
            print $$results{$_}[$i]."\n";            
        }
    }

Which blatantly refuses to work. I've used a similar technique before, but that was with a straight hash, not a reference to a hash? Does it make a difference??

Please help pingu so he can go to sleep happy tonight.
