Great! Just what I was looking for! Can I use the below mentioned approach to arrive at the same result?

if ($arr =~ /(\w*)(abc)(\d{5})/){ $a = $3 if (($arr =~ / (\w*)(def)(\d{8})/){ $b = $3 } } print $a; prnit $b;

    Yes.  But don't use $a and $b :)  — they're special global variables (for sort).

      Alright!! Thank you!! Let me see how sort works now :-)

    Also remember that if either (or both) or the regexes fail to match, one or the other (or both) of  $a and  $b (or whatever you finally decide to call them) will be undefined.
