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

Thanks to blakem and mirod my code looks like this.

#!/usr/bin/perl use strict; use diagnostics; use Time::Local; my (@records, @report); { my $data_file = 'test.dat'; open my $fh, $data_file or die "Can't open $data_file: $!"; while (<$fh>) { # skip blank and commented lines next if /^\s*#/; next if /^\s*$/; chomp; # We'll look for lines that describe a report: if (/report:\s+sort\s+(\S*)/ ) { @report = split /,/, $1; } else { push @records, [split /,/]; } } } my %field = ( source => 0, time => 1, sip => 2, sport => 3, dip => 4, dport => 5, hits => 6, acl => 7, lnum => 8 ); my (@sort_sub, @sort_description); # Here is where we do the sub building foreach (@report) { my ($name, $order) = split /-/; my $cmp = $name =~ /source|time/ ? 'cmp' : '<=>'; if ($order eq 'd') { push @sort_sub, qq|\@\$::b[$field{$name}] $cmp \@\$::a[$field{$name}]|; push @sort_description, qq|$name:\t\tdescending|; } else { push @sort_sub, qq|\@\$::a[$field{$name}] $cmp \@\$::b[$field{$name}]|; push @sort_description, qq|$name:\t\tascending|; } } # require ''; # created with begin my $date = localtime; $date =~ s/ /-/g; ### store report data in file my $report_file_name = 'out.txt'; open my $fh, '>', $report_file_name or die "Can't Open $report_file_name: $!"; print $fh qq|\t\tREQUEST FOR SORTING\n\n|, sort_description(), "\n\n", qq|FILE WAS GENERATED ON: $date \n\n|; my $sort = column_sort(\@sort_sub); print $fh (join ',', @$_), "\n" for sort $sort @records; sub column_sort { my $ref = shift; my $sort_sub = join " || ", @$ref; return eval "sub { $sort_sub }"; } sub sort_description { return join "\n", @sort_description; } __END__

Thanks for the help,
