I have a Java program that does some String matching. I'm looking for anything that matches \d+x\d+ in a String. This works, using the Pattern and Matcher classes.

I have been banging my head against this for some time now: I want to capture all [a-z]+[0-9]? character sequences excluding strings such as sin|cos|tan etc. So having done my regex homework the following regex should work: (?:(?!(sin|cos|tan)))\b[a-z]+[0-9]?

SA "239.255.252.1", SB "239.255.252.2...
