You have put your finger on the reason that XSLT is different from a programming language. XSLT is not turing complete which means that there are a variety of optimizations and checks that can be applied that are impossible to provide in a programming language. It also means that XSL is easier to learn than an XML-optimized programming language because the set of concepts is much smaller than the combination of a programming language AND a sophisticated XML parsing/searching/traversing library. XML and XSLT both live on one side of the declarative/Turing-complete fence. Scripting languages live on the other side. We need both. -- Paul Prescod - ISOGEN Consulting Engineer speaking for only himself http://itrc.uwaterloo.ca/~papresco The first three Noble Truths of Python: All that is not Python is suffering.
