Yes. Parsing presumes a human-readable language. HTML was meant to be human-readable. > I mean, that's why it's not Regular and you [therefore] can't use RegEx for it. It is a different matter. There are classes of formal languages. Regular expressions belong to such a class. If some language is out of the class its sentences cannot be recognized/described/generated. This is not directly related to parsing and parsing is only partially about recognizing valid statements. A parser must also deal with invalid ones in order to provide meaningful diagnostics and have an output, beyond just yes-no. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
