fn:sort
Sorts a supplied sequence, based on the value of a sort key supplied as a function, using
the supplied collation. Calling the single-argument version of the function is equivalent
to calling the 3-argument form with fn:default-collation() as the second
argument and fn:data#1 as the third argument: that is, it sorts a sequence of
items according to the typed value of the items.
sort($input as item()*, $collation as xs:string?:=fn:default-collation(), $key as fn(item()) as xs:anyAtomicType*:=fn:data#1) ➔ item()*
Arguments | ||||
| $input | item()* | The input sequence to be sorted | |
| $collation | xs:string? | := fn:default-collation() | The collation used for comparing strings |
| $key | fn(item()) as xs:anyAtomicType* | := fn:data#1 | The sort key |
Result | item()* | |||
