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;

and the output is: 
tag 0: [lls foo]                                                      
+          
tag 1: [some randome tag]
tag 2: [last_tag]

Is that what you're looking for?
