Here is an approach that worked on the data you provided. I think it would replace your foreach loop.
Although, I'm not sure how you want your data printed with a '<br>' at the end of each line.

#!/usr/bin/perl use strict; use warnings; use 5.014; my ($file, $function, $tag); printf "%-5s%-15s%s\n", qw/ Tags Function File /; my @line = <DATA>; for my $i (0 .. $#line) { if ($line[$i] =~ /^File: (.+)$/) { $file = $1; } elsif ($line[$i] =~ /^Function: (.+)$/) { $function = $1; } elsif ($line[$i] =~ /^Tag: Yes$/) { ($tag) = $line[$i+1] =~ /(\d+)$/; printf "%-5s%-15s%s\n", $tag, $function, $file; } } __DATA__ File: check1.asm Function: Monks Tag: No Tag: 001 Tag: Yes Tag: 002 File: check2.asm Function: Perl Monks Tag: Yes Tag: 003 Tag: No Tag: 004 File: check3.asm Function: Experts Tag: No Tag: 005 Tag: No Tag: 006 Function: Perl Experts Tag: No Tag: 007 Tag: Yes Tag: 008
