Hi all,

Looking to see how to create a pattern for regular expressions to say "does not include the string ____"

More specifically, I'm looking for a single pattern to say "starts with 'abc', ends with 'ghi', but does not contain the string 'def'"
Something along the lines of "abc.*^(def).*ghi" which obviously wont work

Where "abcdefghi" will not be a match, but "abcfedghi" would

Any ideas?
Matt
