Given a yang list of Data Nodes

under a know parent (path to parent is known)  TBC

user wants to find element(s) where a leaf (attribute) has a certain value 

e.g. 

\ran-inventory\sliceProfilesList[{id=1, sNSSAI="a", latency=5}.
                                                  

{id=2, sNSSAI="b", latency=6}

,
                                                  {id=3, sNSSAI="a", latency=6}]

the user want to find the elment in SlicePofileList taht as an sNSSAI valueof "b"

but he knows that the xPath 'starts with' \ran-inventory\sliceProfileList'  ([

 

Solution Proposal

Filter out correct data in the Persistence layer (not in higher layers, waste of data transfer etc.)

• use query of cpsPath starting with given path (maybe even add '[')
• use json-query tools to only get the 'fragment' that contain required name-value pair
  (probably need native-query annotation)

 PoC: Try a hardcoded db integration test.  SQL data insert would use (xpath, attributes) values like:

/ran-inventory/sliceProfilesList[@id=1],  {"id": 1, "sNSSAI": "a", "latency": 5}

/ran-inventory/sliceProfilesList[@id=2],  {"id": 2, "sNSSAI": "b", "latency": 6}
