Select all A elements that are the child of the document root [note] That has a descendent element named C that has an attribute with name name and value "something" note there will be at most one element child of / in a well formed document, although the Xpath data model potentially allows processing of fragments with more than one top level element) > I assume this Path expression goes into an XML attribute as a string, > perhaps the T Processor, so its evaluation would be dependent on > context. I have no idea what you mean here, so I can't really comment. The value of the expression is a node set which will consist of zero or more element nodes, (at most 1 if the input is well formed).
