Sam - This is done using Regular Expressions, and the SEARCHREGEX( ) function. We have sent you various versions of RegEx that do this with increasing degrees of sophistication.
Tom - it would be useful to see those options... I think RegEx is one area where non-programmers can feel a little daunted, but it's such a powerful capability.
A couple of resources that I find very handy when developing/testing RegEx, for non-programmers like me:
1. http://www.regular-expressions.info/ - provides a great overview and tutorials on Regular Expressions 2. http://gskinner.com/RegExr/ - on online RegEx editor/test environment... cut and past Omniscope data into the large mult-line window and then enter RegEx above and test as you go!
