...to spend on hardware to make up for the verbosity and parsing pain of XML. What did facebook just do? Spend a score or so of man-years on a ``skunk works'' project to speed up their PHP spaghetti by automatically translating it into C++? So they could cut on hardware?
Oh, and it's ``regex'', short for ``REGular EXpression'', not ``RegX''. Unless you mean something entirely different that I'm not aware of.
