JsltJsonFilter clarification

[ronMilne]

Can a jslt filter achieve the following?

Given the Json

{
  "clientNames": [
    {
      "type": "Name",
      "clientNameTypeCode": 634,
      "startDate": "2022-09-06",
      "inModeCode": "U"
    }
  ],
  "client": {
    "clientIdentifiers": [
      {
        "identifierTypeCode": 25,
        "identifierStatus": "REGD",
        "identifierStartDate": "2022-09-06"
      },
      {
        "identifierTypeCode": 525,
        "identifierTypeCodeDecode": "Entity",
        "identifierLatestIndicator": "Y",
        "identifierStartDate": "2022-09-06",
        "inModeCode": "I"
      }
    ],
    "clientInternalId": "<<unknown>>",
    "Id": "1d21044e7cd4a593c2046503a09dc653"
  },
  "domain": "clients"
}

I need the tree structure to only include nodes that contain inModeCode and produce the following

{
  "clientNames": [
    {
      "type": "Name",
      "clientNameTypeCode": 634,
      "startDate": "2022-09-06",
      "inModeCode": "U"
    }
  ],
  "client": {
    "clientIdentifiers": [
      {
        "identifierTypeCode": 525,
        "identifierTypeCodeDecode": "Entity",
        "identifierLatestIndicator": "Y",
        "identifierStartDate": "2022-09-06",
        "inModeCode": "I"
      }
    ]
  }
}

Any help in how to achieve this would be greatly appreciated.
