When reviewing the solution given, I realized in my initial try I was using [::alpha::] to search for any letter characters as per Alteryx's listing of regular expression choices. The solution uses [[:alpha:]]. Correct me if I am wrong but it seems that it's a POSIX expression used within a bracket expression in order to differentiate it as POSIX but still do not understand the use of one less colon on each either side of "alpha". Can someone explain?
I hate RegEx, i get its powerfull but i hate writing it.
