Usage Notes
An object-node() is constructed from a
json:object, a map:map, or an
object-node().
An array-node() is constructed from a
json:array, a sequence of multiple items, or an
array-node().
A null-node() is constructed from an empty sequence or
an null-node().
A boolean-node() is constructed from an
xs:boolean or a boolean-node().
A number-node() is constructed from an
xs:integer, a xs:decimal, a
xs:float, a xs:double, or a
number-node(). Integers with absolute value greater than
9007199254740991 are excluded and instead construct text()
nodes to avoid any loss of precision.
A text() node is constructed from all other items.
To serialize a JSON node to a string, use xdmp:quote.
Example
xdmp:to-json(("a",fn:false()))
=>
["a", false]
Example
let $object := json:object()
let $_ := map:put($object,"a",111)
return xdmp:to-json($object)
=>
{"a":111}
