This is true, though my code is likely faster.

Nah. You've made your point.. in fact I was secretly trying to help. <g>

Regex is a good general purpose string parsing facility. I personally find  
composing a regex can be complicated, likely it's easier with practice. A  
custom piece of code is probably faster and I find it easier to tweak. In  
the end, unless it was performance critical or has resisted my initial  
efforts at composing a regex, I'd probably use a regex.
