What I want to do is take a string such as "this.those.that" and get a substring to or from the nth occurrence of a character. So, from the start of the string to the 2nd occurrence of . would return "this.those". Likewise, from the 2nd occurrence of . to the end of the string would return "that". Sorry if my question is foggy, it's not that easy to explain. Also, please do not suggest making extra variables, and the result will be in a string and not an array.
