Re^4: check if string is valid with special cases

Ok I understand, forget about commas in the substrings.
your regex is good and its what I need except it doesn't handle an empty space case: "a,b,c, d,e" (bad case).
how can I add it to the regex?

Again, more examples please. Only literal spaces? I am guessing you mean one or more spaces? What about other whitespace? Is `" x ,..."` valid? Is `" x y ,..."`? What is the expected output for those cases? And so on.	[reply] [d/l] [select]
