Hi Bruce, Not sure if "()" always indicates function call. XPath 1.0 grammar says PathExpr = FilterExpr | . . . [ignoring others like LocationPath for ] FilterExpr = PrimaryExpr | FilterExpr Predicate PrimaryExpr = '(' Expr ')' | . . . [others too in the list, ignoring them for convenience] Where Expr is an 'OrExpr', which can be another PathExpr. See [19] in section 3.1 of Xpath 1.0 specification.[http://www.w3.org/TR/xpath] -Menon On 5/2/05, Bruce D'Arcus <bdarcus@xxxxxxxxx> wrote: > On 5/2/05, Ramkumar Menon <ramkumar.menon@xxxxxxxxx> wrote: > > > Sorry for not being clear enough, but I had meant to ask "why are > > patterns like (foo) or (/child::foo) considered invalid patterns as > > per XSLT specification ?" > > Curious as to whether this kind of a pattern breaks any semantics of XSLT . > > rgds, > > I'll let someone else step in to correct me if I get the language wrong, but: > > / or foo are nodes, while () indicates a function call.

Pop up, push down, byte, byte, byte! -Ramkumar Menon A typical Macroprocessor
