Michael, I almost laughed out aload reading your message.... > XML removes the necessity of defining YACC grammars > and writing parsers for every random data > format need. only funny because I remember YACC from way back. No doubt it still exists. I remember that was one heck of a frustrating program. and yet... some of these new tools have exactly the same frustration level in xml even now. I don't know why I think that, but it seems that way to me. Especially in Linux. You have some interesting points to make in any case.
