Sorry I posted in the wrong section first 
but could not delete the post… So here it is appropriate :
Hello, I have the following document and wonder whether I can retrieve all the “A” sorted, first, by B, then by @C. (If two A have the same value for B, sort them by @C).
bb
<C @C=“c”/>
[series of other ]
I use version 3.1.1 of Tamino. Thanks.
Try the following query…
root/A sortby (.,./B,./C/@C)
