try {
JSONObject xmlJSONObj = XML.toJSONObject(TEST_XML_STRING);
Object header=xmlJSONObj.get("S:Envelope");
JSONObject jsonObject = start.getJSONObject(0);
JSONArray dependencies = jsonObject.getJSONArray("list");
JSONArray dependencies = jsonObject.getJSONArray("getData");
String data = dependencies.getString(0);
System.out.println(data);
} catch (JSONException je) {
System.out.println(je.toString());
}

I have used JAXB is past but as this is for our Automation scripts and i want see if JSON can be used here, so that i don't have any dependencies on WSDL. "Object header=xmlJSONObj.get("S:Envelope");" does provide me header and other details but if i need vehicleInfo i will have to create object for all other parent tags.

Answer 1

I am able to resolve issue, it was issue with JSONObject, i was trying to access child node in below sequence.

test=xmlJSONObj.getJSONObject("S:Envelope").getJSONObject("S:Header").getJSONObject("").getJSONObject("ns7:NewPORequest").getString("ns7:tracingLevel");

Problem here is that when SOAP Messages gets converted into JSON, the header doesn't have any value, by removing header from my string i am able to get node values.

String test=xmlJSONObj.getJSONObject("S:Envelope").getJSONObject("S:Body").getJSONObject("ns7:NewPORequest").getString("ns7:userId");
