Not entirely clear what you want... so I'm guessing a bit.

#!/usr/bin/env perl5.22.1

use strict;
use warnings;
use 5.10.1;

my $x ="aaa bbb ccc dd ee ff dd TAG=lls foo TAG=some randome tag TAG=l
+ast_tag";
#my $x ="TAG=lls foo TAG=some randome tag TAG=last_tag";

my @tags = split /\s*TAG=/, $x;

# before the first TAG, discard.
shift @tags;

my $i = 0;
say "tag ", $i++, ": [$_]" for @tags;
[download]

and the output is:

tag 0: [lls foo]                                                      
+          
tag 1: [some randome tag]
tag 2: [last_tag]
[download]

Is that what you're looking for?

It is exactly what I was looking for, only I was trying to be a bit clever (or not) and wanted to shorten it into a single REGEX. --- thank you for your reply	[reply]

Tanktalus's split approach is probably better, but here's a "clever (or not) ... single regex" that produces the same output: `c:\@Work\Perl\monks>perl -wMstrict -MData::Dump -le "use 5.010; ;; my $s = 'aaa bbb ccc dd ee ff dd TAG=lls foo TAG=some randome tag TAG +=last_tag'; ;; my @ra = $s =~ m{ TAG \s* = \K (?: (?! \s* TAG) .)* }xmsg; dd \@ra; " ["lls foo", "some randome tag", "last_tag"]` [download] (Needs 5.10+ for the `\K` regex operator.) Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
