Here's a quick stab at a solution. It works with your example data...

use strict; use Data::Dumper; my %hash; my $regexp = qr{ ^ \s* Collection \s* => \s* (\d+)? \s* ImageCount \s* => \s* (\d+)? \s* Status \s* => \s* (\w+)? \s* Missing \s* => \s* ([\d,]+)? \s* Modified \s* => \s* ([\d/]+\s[\d:]+)? \s* $}x; while (defined(my $line = <DATA>)) { chomp $line; my %linehash; if ($line =~ $regexp) { %linehash = ( Collection => $1, ImageCount => $2, Status => $3, Missing => $4, Modified => $5, ); } next unless defined $linehash{Collection}; $hash{ $linehash{Collection} } = \%linehash; } my @sorted_by_status = sort { $a->{Status} cmp $b->{Status} } values % +hash; print Dumper \@sorted_by_status; __DATA__ Collection=>168245 ImageCount=>6 Status=>SI Missing=>1,3 Modified=>01/ +18/2012 11:14:30 Collection=>161745 ImageCount=>6 Status=>I Missing=>2,3 Modified=>01/1 +8/2012 11:16:38 Collection=>162451 ImageCount=>6 Status=>SC Missing=> Modified=>01/20/ +2012 11:16:38 Collection=>117481 ImageCount=>8 Status=>C Missing=> Modified=>01/18/2 +011 7:16:38

It would be nice if the regular expression could be made less specific, but some features of your data format make that tricky (e.g. the fact that the value following "=>" can be a zero-length string).
