Hello,
I would like to experiment with map features in Saxon
(http://www.saxonica.com/documentation/expressions/xpath30maps.xml), but I am
unable to get past query compilation. Maybe I am missing some parameter or I
use a wrong namespace, but I just can't find the right answer.
I was rather hoping that the W3C spec would be out before the Saxon
implementation, but it got held up because people in the XQuery WG
didn't want it in XQuery 3.0. The net result is that there's a shortage
of documentation.
The page at http://www.saxonica.com/documentation/extensions/map.xml
wrongly gives the namespace as "http://ns.saxonica.com/map";. In fact, in
the over-optimistic belief that the spec was about to be approved by
W3C, I moved the functions into the namespace
"http://www.w3.org/2005/xpath-functions/map";.
This is my query code:
xquery version "3.0";
(: i have also tried http://www.w3.org/2005/xpath-functions/map, no difference
:)
import module namespace map = "http://ns.saxonica.com/map";;
map:get(map { 1 := 'aaa'}, 1)
For vendor-defined extension functions in Saxon, you don't need an
import module, but you do need to declare the namespace. So it should be
xquery version "3.0";
declare namespace map := "http://www.w3.org/2005/xpath-functions/map";;
map:get(map { 1 := 'aaa'}, 1)
