xquery question on copy and update

Hi Everyone, Still in my quest to make angularjs and basex work without other serverside solutions. I'm trying to copy a node and to update an attribute before adding it to the db. (:~ : Add datamodel node types :) declare %rest:path("/addNodeTypes") %output:method("json") %output:json("format=attributes") %output:json("lax=yes") function _:addNodeTypes( ) { let $db := db:open("simplePLM_test1") let $insert-node := $db//objectType[@name="nodes"]/template/nodeType return copy $copyNode := $insert-node modify ( replace value of node $insert-node/@id with 100, insert node $insert-node as first into $db//nodeTypes ) return $copyNode }; The syntax seems ok but I get this error which I don't really understand : <title>Error 400 Stopped at C:/Program Files (x86)/BaseX/webapp/BOM/BOM.xqm, 85/55: [XUDY0014] db:open-pre("simplePLM_test1",17) was not created by copy clause.</title> </head> <body><h2>HTTP ERROR 400</h2> <p>Problem accessing /addNodeTypes.

Hi Yoann,

In the copy clause, you need to specify the node which is to be modified: Old: copy $copyNode := $insert-node New: copy $copyNode := $db Hope this helps, Christian
