Implement the functionality to support multiple nodes replacement using data fragment with list-node as a root element.

replacing one or more list elements that already may exists (same-key). Al old element that are not in the new payload will be deleted

Data JSON example:

// references test-tree.yang (see cps-service test)
{
  "branch": [
    { "name": "one"},
    { "name": "two"}
  ]
}

A/C

REST layer (incl. openapi update)

• uri:
  • (CPS) PATCH /dataspaces/{dataspaceName}/anchor/{anchorName}/list-node
  •  (NCMP) PATCH /cm-handle/{cmHandle}/list-node
    • (NCMP REST interface not final might change later)

• parameters:

• • xpath - parent node xpath (mandatory)
  • JSON data fragment via request body
• response 200 on success
• if empty list provided treat as validation exception

Service layer

• parse JSON string into collection of DataNode objects

Persistence layer

• extract list-node xpath identifier from data nodes provided
• find parent node by parent node xpath (throw not found exception if absent)
• remove all children matching (starting with) list-node xpath identifier
• add all provided elements to parent node
• persist

out of scope

• system will replace even if all content is identical
