Any improvement would be minor, I think. The cost of actually inserting the new fragment will swamp the extra CPU cost of evaluating a few XQuery functions, and all the data used by the XQuery function would have to be brought into memory either way.
I think the philosophy here is that this *can* be done in pure XQuery. So do it in pure XQuery, and show that people use it. That will help convince product management that it would be useful inside the server. Personally I hardly ever rename documents: I try to design databases so that the document URIs are meaningful and are based on something immutable and unique within the document structure. -- Mike On 29 Jun 2011, at 10:20 , Geert Josten wrote: > Another argument in favor of a built-in function would be performance gain, > if that is likely.
