Make yourself familiar with regular expressions and then come back to us.
Here is a website which lets you easily test RegExes:

EDIT
As I can see you already asked for filters in various other threads e.g.:

--> As said, RegEsx is something you have to learn like math - we're neither here to teach you this nor are we there to always tell you the result of your homework
