Hi changalrai......i hope my following code will help you. Suppose that your data is in SOPW.txt file .The the following code will retrieve what you wanted.

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

open (my $fh, "<", "c:/SOPW.txt") or die "can't open the file :$!";

while (<$fh>){
    chomp;
    if(m/\w+:(.*);/){
        print "$1\n";
    }
}
