Regular expressions match sequences of characters. Your match says to match a string when both of 2 different matching possibilities exist anywhere in the string. To do this you must use 2 separate regular expression matches separating them by the normal C++ "&&" operator.
Maybe I'm misunderstanding what's wanted, but wouldn't is.*a do what he wants? Or if they need to be matched in either order: (is.*a)|(a.*is) It doesn't scale well, of course. -- Dan Ellis, Software Engineer, Sophos Anti-Virus Email: dan.ellis@sophos.com, DDI: 01235 540204 Real Business/CBI Growing Business Awards: Company of the Year Tel: 01235 559933, Web: http://www.sophos.com/

Yes, that should do it. It was my mistake to suggest that two matches would have to be used.
