in thread How to Extract Nested IF/THEN elements

What my first sentence meant to say was:

A formal regular expression can only match an arbitrarily nested structure. Thus if we wanted to match to depth of say 6 we could do it, but if we want to match to any depth a formal regex wont work. And as I said above perls regexes arent formal regexes. They are decidedly irregular as they have support for backrefs.
