FunctX XSLT Functions

functx:sort

Sorts a sequence of values or nodes

Google

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.

Arguments and Return Type

NameTypeDescription
$seq item()* the sequence to sort
return value item()*
