As far as I know, you have to differentiate between insert and replace
scenarios when using the xdmp:node-XXXX functions:
doc("/my-doc.json")/xdmp:node-insert-child(object-node(), object-node {
"PropName" : "PropValue" }/PropName)
doc("/my-doc.json")/xdmp:node-replace(PropName, object-node { "PropName" :
"PropValue" }/PropName)
If you try to reinsert a property with the same name, you will get an
exception. If you need insert-or-replace behavior, though, you could wrap the
xdmp:node-replace call in a try/catch and call xdmp:node-insert-child in the
catch block when the exception thrown is XDMP-CHILDDUPNAME.
