<p>Hi</p>
<p>Please take a note about the regular expressions here [href://http://perldoc.perl.org/perlretut.html] and do you want something like this?</p>
<c>
use strict;
my $string = "Required Not_Required Not_Required Required";
while($string=~/\bRequired\b/gi){
print "$&\n";##Here it will print only required text with non word character before and after
}
</c>
