Return object with maximum value from item sequence.
fn:max(sequence $sequence) => anySimpleType?
fn:max(sequence $sequence, string $collation) => anySimpleType?
This aggregate function returns the maximum value of all values in a
sequence that are of a single type or one of its subtypes, for which the
gt operator is defined. For numeric values type promotion is used
to coerce all values to a single common type. If the argument is the empty
sequence, the function returns the empty sequence.
| $sequence |
a sequence of items |
|---|---|
| $collation |
optional valid collation string literal |
Get maximum value from sequence with numeric values:
