Traditionally, RE can't do this kind of balanced matching. Modern perl 5.10s have special support for it and even older perls have special (?{ code }) matchers than can do the counting for you. What you really want is a parser.

Your best bet is probably: Text::Balanced rather than RE. Although, to be honest, I've done it both ways and prefer using (?{ code }) to T::B as I find it difficult to operate.
