Store the sets of lines in an array of arrays (AoA)

#!/usr/bin/perl use strict; my $flag = 0; my @lines = (); my @set = (); while (<DATA>){ if (/^\s*END/){ $flag = 0; push @set,[@lines]; } elsif (/^\s*START/){ $flag = 1; @lines = (); } elsif ($flag) { push @lines,$_; } } my $n = 1; # first set print join '',@{$set[$n-1]}; $n = 3; # third set print join '',@{$set[$n-1]}; __DATA__ XXX YYYY START These are the first set of lines which are to be extracted END START These are the second set of lines which are to be extracted END XXX ZZZ YYY START These are the third set of lines which are to be extracted END aasds tteret tertetr
