Is the following expression legal?
count(//|//@*)
I don't think so, // is a short form of /descendant-or-self::node()/ and
according to grammar rule 3
[3] RelativeLocationPath ::= Step |
RelativeLocationPath '/' Step | AbbreviatedRelativeLocationPath
requires Step after last "/".
It is supposed to count all nodes and attributes from the current context
node.
So, do as you said:
count(//node()|//@*)
The reason I'm asking is that I'm currently evaluating a few different XSLT
processers, with a view to using one of them in a product I'm working on.
I've noticed that different processers handle it differently, the main
stumbling block being the "//" by itself.
Usually, they work separately (i.e. count(//) and count(//@*) ), but a
couple (e.g. Apache's XalanC) seem to fall over when they are combined as
above.
Huh, interesting point, can you say where count(//) works? This
expression have to raise syntax error.
