Re^2: File Parsing

[shortyfw06]

The example in the original post is one step in my overall goal. In moving forward, I think I do want a hash, however, the hash value for key 1 should be @array. Then the @array is undefined and the next match creates a new @array with is then the hash value for key 2. This process is repeated until all matches have been found in the file for each element in @headers. I am really struggling with this one.... I hope my explanation is clear. Here is my attempt at this.

#!usr/bin/perl
use Tk;
use Cwd;
use strict;
use warnings;

            if ($line =~ /$headers[$n-1]/) {
                undef @array;  #This clears the previous two instances
