Hello,

The content of DATA are modified  %hash value. Need to include  %hash key before or after  SOME_DATA to respective modified  %hash key

Don't know how to search modified  value and include respective  key after or before  SOME_DATA 

__HASH__

$VAR1 = {
'Key1' => 'Cat.Mouse.Game.Lion.Tiger.Elephant',
'Key2' => 'Cat.Mouse.Game.Lion.Tiger.Lion',
'Key3' => 'Cat.Mouse.Game.Lion.Tiger.Monkey',
};

__DATA__

Pigeon.Lion.Tiger.Elephant SOME_DATA
Pigeon.Lion.Tiger.Lion SOME_DATA
Pigeon.Lion.Tiger.Monkey SOME_DATA

__Example code__

my %hash = ()
my $file = 'master.txt';
open (my $OUT_FILE, '<', "TEXT_FILE") or die "ERROR";

while (<$OUT_FILE>)  {   
    print "$. \n" if /SOME_DATA/; #searching SOME_DATA and printing
}

__OUTPUT__

Pigeon.Lion.Tiger.Elephant SOME_DATA (Key1)
Pigeon.Lion.Tiger.Monkey SOME_DATA (Key3)

UPDATED:

%hash value "Cat.Mouse.Game" is replaced with "Pigeon" and placed in a text file along with SOME_DATA

Ignore "Pigeon" and match other characters. If there is a match, then include respective %hash Key before "SOME_DATA"
