Regex if then to return if found else look for next item : Not sure, but haven't found the right answer for this using Regex.  I have three words which may all be present in the text - say 'one two three'.  I want to use regex to search for 'one' and return if found and stop so I get 'one' only. If 'one' is not found look for 'two' and finally if not found simply match 'three'. PCRE format will work.
