Saxon descending order

To get elements in ascending order with saxon we write this...

saxon:sort(sale, saxon:expression('@price * @qty'))

How to get 开发者_运维知识库the elements in descending order?

Thank you in advance.

Why not

saxon:sort(sale, -saxon:expression('@price * @qty'))

Or perhaps

reverse(saxon:sort(sale, saxon:expression('@price * @qty')))

Or for more flexibility you might try moving from XPath to XQuery (depending on your environment and constraints).
