Recently you have posted many times (>20) regarding regular expressions, again here you show no code or any effort you have made to do this yourself. Previous replies have pointed you towards the documentation.

What are you having a problem with here? Since you post no code it looks like you are simply asking for someone to do this task for you. This site is not a code production service. See Corion's notes on problems solving in a previous reply to one of your posts.
