Hi Florent,
You are effectively passing an unnamed (root) object-node with a single
property as argument, whereas the node function is expecting the (named)
property itself. In XQuery you would append /text() after your JSON to fix
that:
xdmp:node-insert-child(doc("/test.json")/object-node(), object-node{ "c":
"d" }/text())
But I don¹t think that will work in JS..
On the other hand, why don¹t you convert the JSON node to a real JS JSON
object, manipulate that in the old fashion JS way, and insert that back
into the db? Might be much more practical, particularly if you are making
multiple changes..
Cheers
