Intuitively I would expect them to be sorted in the order in | which they were created, but as far as I can tell the formal semantics | leaves this unspecified. Your expectation is met: the resulting list of <c> elements is in creation order as you name it. Document order sorted node lists are created when XPath location steps are applied to a given (however sorted) sequence of context nodes. This does not apply for your example, however. My students stumble about the distinction all the time: $list/axis::nodetest is not equivalent to for $n in $list return $n/axis::nodetest Best wishes, --Torsten -- | Dr. Torsten Grust Torsten.Grust@uni-konstanz.de | | http://www.inf.uni-konstanz.de/~grust/ | | Database Research Group, University of Konstanz (Lake Constance/Germany) | | (Please avoid sending me MS Word or PowerPoint attachments.) |Received on Tuesday, 23 September 2003 09:41:11 UTC
