Hello rahulme81,

beside the wisdom received from brother choroba you can find interesting the read of Using Look-ahead and Look-behind.

Also the precious resource of wisdom Modern Perl (the free book!) has a chapter dedicated to regexes: look for the Assertions paragraph in chapter 6

L*

There are no rules, there are no thumbs..
Reinvent the wheel, then learn The Wheel; may be one day you reinvent one of THE WHEELS.
