Why don't you use more regular expressions?

I have decided not to make extensive use regular expressions for 2 reasons. First, I HATE regular expressions. I find them extremely annoying. Second, my goal is to make sure that the javascript and php versions of the HCL function exactly the same. Regular Expressions can sometimes have slight differences between the two languages. So I have decided to avoid regular expressions to avoid any chance at differences in regular expressions causing a difference in functionality between the two language implementations.
