[QUOTE="Joe Kesselman, post: 3086842"] Depends on the predicate. If p2 or p3 tests position() or last(), _NO_ -- the latter form would test position in the original set, while the former would test position in the set that has gotten past the preceeding filter(s). In these examples: no, since an absolute XPath by definition ignores its context and since if it fails in any of these the result is that we find no nodes. (Though for performance reasons in typical processors, you will probably want to test it earlier rather than later). In more complicated XPaths, maybe. [/QUOTE]
