This is actually very straightforward. "return" is a keyword, used in FLWOR expressions and a few other places. There is no standalone "return" in XQuery. Thus: let $x:=0 return (23) is a valid (if uninteresting) FLWOR expression that is equivalent to the even less inte . . . Read full entry »

Simple (I thought) Xquery giving run-time error.

Posted 7/13/2012 8:20:41 AM

It seems like you might have too many '/*' steps. For example, if you evaluate $models/* in the body, I think you should get the empty sequence. $models appears to bind to the sequence of <Model> elements so $models/* would select element children of each but there aren't any.

Your problem is that the initialization of $models goes down two levels below the document node, so it is bound to a sequence of Model elements, so when you do $models/* you are selecting the children of the Model elements, but there are no child elements to select.

XQuery Update Facility and unwanted whitespace

Andrew has answered the whitespace questions. It's a Saxon (not an Oxygen) restriction that XQuery 3.0 and XQuery Update can't currently be used together in the same query.
