( #3333=superdoc: print w/ replies, xml ) Need Help??

Schwartzian, no doubt, but not enough transformation. The dates are originally in DD-MM-YYYY format and must be rearranged for effective sorting.

@dates = map { $_->[0] } sort { $a->[1] >= $b->[1] } map { my $f = $_; /(\d\d)-(\d\d)-(\d{4})/g; [ $f, "$3$2$1" ] } @dates;

Also, incomplete. There are 3 other columns that should figure in the sort. I'd like to see the OP's code.

On a side note, I had never heard of the ST before. I looked briefly in perlsyn to see how I would know that the map {} sort {} map {} would be executed in reverse order, but I didn't find it. Any clues?
