functx:sort

Sorts a sequence of values or nodes

Description

The functx:sort function sorts a sequence of values or nodes. If nodes are provided, their typed values are compared (if they are untyped, they are treated like strings.) Although this can easily be accomplished with an order by clause, calling this function makes the query less verbose because you can avoid writing a FLWOR expression solely to sort the values.
