Remove outermost node from the JSON payload-CodePudding

I need to remove the outermost element(ns0:TableData) from the below JSON paylaod.

{
    "ns0:TableData": {
        "descr": 111,
        "note": 11,
        "kpar": 1111,
        "karr": 111,
        "xmlns:ns0": "urn:it:alia:inaz",
        "codice": 1,
        "dend": 1111,
        "anz_app_a": 1,
        "dini": 11
    }
}

I am using the below code to covert the incoming XML to JSON

String inputData = IOUtils.toString(inputstream);
System.out.println(inputData);
JSONObject xmlJSONObj = XML.toJSONObject(inputData);
String jsonPrettyPrintString = xmlJSONObj.toString(PRETTY_PRINT_INDENT_FACTOR);
System.out.println(jsonPrettyPrintString);

In XPath 3.1, use json-doc('input.json')?*
