[xquery-talk] How to Reverse an Array

[Ghislain Fourny]

Hi Eliot,

Forget what I said: there is actually a function for this :-)

array:reverse($array).

http://www.w3.org/TR/xpath-functions-31/#func-array-reverse

But the approach in the other query works for any other function.

Kind regards,
Ghislain
