G'day ImJustAFriend,

Looking at the code you've posted, I'm wondering if you were trying to adapt the solution I provided to you in "Re: Multiple Line Regex Not Working". If so, it seems there may be some part(s) you didn't understand. Please ask if this is still the case.

I put your input data in a file this time and wrote the following script. Compare it with the last one.

#!/usr/bin/env perl

use strict;
use warnings;
use autodie;

my $file = 'pm_1226079_input.txt';
my $SEP = '-' x 40 . "\n";

open my $fh, '<', $file;

{
    local $/ = "\n******************* NRG location";

    while (<$fh>) {
        chomp;
        /parameters after change .+?\n(.*)\z/ms && print "$SEP$1\n";
    }
}

Notes:

• Use a lexical filehandle. See open.
• Always localise changes to special variables in the smallest scope possible. These are global variables and you don't want these changes propagated throughout your entire script. See also perlvar (and its multiple uses of local throughout).
• The autodie pragma takes care of all of the "... or die "...";" parts of your script. It saves you having to write them: they're easy to forget; and easy to get wrong (such as leaving out the name of the file that failed to open :-)

Here's the output from that script:
