Gummo, I'm aware of that could happen, and if you want to get technical, there will always be a "what-if possibility" to take into consideration. I wasn't being meticulous when it came to matching in the regex. I was basically copying if off from the example shown above my initial post for a quick solution. Nevertheless, though, I agree with you about using the "negative lookaround" method to enhance the foolproof level of regex.
