Is there a way to update items in an array with JsonPatch?

The API to be invoked uses JsonPatch. The following is a sample JSON.

  { "hello": false
  , "array1": 
    [ { "subarray": [ "k2", "k1"] } 
    , { "subarray": [ "k1"] } 
    ] 
  }

I would like to update both the subarrays (elements of the array1). There could be N number of elements/items in array1 that I'm not aware of when calling this API.

Now I can do the following if I am aware of the the size of array1.

 [{ "op": "add", "path": "/array1/0/subarray/0", "value": "gk" }]
 [{ "op": "add", "path": "/array1/1/subarray/0", "value": "gk" }]

But since I'm not aware of the the size of array1, it does not seem that this can be achieved using JsonPointer. Is there something that can be done to do an update that targets all the elements of array1 (i.e all the subarrays) in one go? Something like this:

 [{ "op": "add", "path": "/array1/*/subarray1/0", "value": "gk-new" }]

After invocation, the resulting subarrays should have an additional element "gk-new" in addition to what they have?

Solution

  • There is no wildcard support in JsonPatch or JsonPointer. Therefore, what is asked in the question is not possible.
