Android ksoap2 namespace prefix

Question

I am writing an Android application that needs to use a wcf SOAP web service using ksoap2.

The data being passed to the web service needs to match that data being sent from ASP.Net

ASP.Net SOAP

<v:Envelope xmlns:i="http://www.w3.org/1999/XMLSchema-instance" xmlns:d="http://www.w3.org/1999/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/">
  <v:Header />
  <v:Body>
    <SaveWaybill xmlns="ClearNamespace">
      <crossWayBill xmlns:n0="http://schemas.datacontract.org/2004/07/CrossWCFService">
        <n0:WayNo>095-090317-1133</n0:WayNo>
        <n0:FinishDateTime>2017-03-09T11:36:03.000Z</n0:FinishDateTime>
        <n0:StartDateTime>2017-03-09T11:33:56.000Z</n0:StartDateTime>
      </crossWayBill>
      <crossWayBillBreakdownItems xmlns:n1="http://schemas.datacontract.org/2004/07/CrossWCFService">
        <n1:CrossService.CrossWaybillBreakdownItem>
          <n1:WayBillItemId>1</n1:WayBillItemId>
          <n1:Quantity>10</n1:Quantity>
        </n1:CrossService.CrossWaybillBreakdownItem>
        <n1:CrossService.CrossWaybillBreakdownItem>
          <n1:WayBillItemId>2</n1:WayBillItemId>
          <n1:Quantity>20</n1:Quantity>
        </n1:CrossService.CrossWaybillBreakdownItem>
        <n1:CrossService.CrossWaybillBreakdownItem>
          <n1:WayBillItemId>3</n1:WayBillItemId>
          <n1:Quantity>30</n1:Quantity>
        </n1:CrossService.CrossWaybillBreakdownItem>
        <n1:CrossService.CrossWaybillBreakdownItem>
          <n1:WayBillItemId>4</n1:WayBillItemId>

          <n1:WayBillItemId>5</n1:WayBillItemId>
          <n1:Quantity>50</n1:Quantity>
        </n1:CrossService.CrossWaybillBreakdownItem>
      </crossWayBillBreakdownItems>
    </SaveWaybill>
  </v:Body>
</v:Envelope>

Java code

SoapObject waybill = new SoapObject("", "crossWayBill");
waybill.addProperty("WayNo", WaybillNumber);
waybill.addProperty("FinishDateTime", FinishDateTime);
waybill.addProperty("StartDateTime", StartDateTime);


SoapObject breakdown = new SoapObject("", "crossWayBillBreakdownItems");
SoapObject counter;
for (XmlNode node : xmlNodes) {
    if (node.node.equalsIgnoreCase("WaybillItemCount")) {
        if (node.nodeHasAttriute()) {
            counter = new SoapObject("", "CrossService.CrossWaybillBreakdownItem");
            counter.addProperty("WayBillItemId", WayBillItemId);
            counter.addProperty("Quantity", Quantity);
            breakdown.addSoapObject(counter);
        }
    }
}

SoapSerializationEnvelope envelope;
try {
    String returnValue = "";
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    request.addProperty("crossWayBill", waybill);
    request.addProperty("crossWayBillBreakdownItems", breakdown);

    envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);

    envelope.dotNet = true;
    envelope.implicitTypes = true;
    envelope.setOutputSoapObject(request);
    envelope.setAddAdornments(false);

    MarshalDate md = new MarshalDate();
    md.register(envelope);

    HttpTransportSE androidHttpTransport = new HttpTransportSE(URI);
    androidHttpTransport.debug = true;
    try {
        androidHttpTransport.call(SOAP_ACTION, envelope);
        Log.d(">>----> request dump", androidHttpTransport.requestDump);
        Log.d("<----<< response dump", androidHttpTransport.responseDump);
    } catch (HttpResponseException ex) {
        Log.e("androidHttpTransport", "doInBackground: Error:\n" + ex.getMessage());
    } catch (XmlPullParserException e1) {
        e1.printStackTrace();
    }

    SoapPrimitive result = (SoapPrimitive) envelope.getResponse();
} catch (Exception e) {
    Log.e("GeneralError", "doInBackground: Error:\n" + e.getMessage());
}

With the above code, I get the following: -

When I specify a namespace on the following 2 lines,

SoapObject waybill = new SoapObject(CROSS_NAMESPACE, "crossWayBill");
SoapObject breakdown = new SoapObject(CROSS_NAMESPACE, "crossWayBillBreakdownItems");

I get: -

How can I get the namespace declaration (xmlns:n0="...") to appear on the crossWayBill & crossWayBillBreakdownItems nodes and have the prefix (n0:) appear on all child nodes but not on the crossWayBill & crossWayBillBreakdownItems nodes?

Answer 1

I got what I wanted by cheating...

Instead of specifying a namespace, I added an attribute to the SoapObject and hard coded the prefix onto the child nodes.

SoapObject waybill = new SoapObject("", "crossWayBill");
waybill.addAttribute("xmlns:n0", "http://schemas.datacontract.org/2004/07/CrossWCFService");
waybill.addProperty("n0:WayNo", WaybillNumber);
waybill.addProperty("n0:FinishDateTime", FinishDateTime);
waybill.addProperty("n0:StartDateTime", StartDateTime);

This gives me the below and my soap request is accepted by the web service

<SaveWaybill xmlns="ClearNamespace">
  <crossWayBill xmlns:n0="http://schemas.datacontract.org/2004/07/CrossWCFService">
    <n0:WayNo>095-090317-1133</n0:WayNo>
    <n0:FinishDateTime>2017-03-09T11:36:03.000Z</n0:FinishDateTime>
    <n0:StartDateTime>2017-03-09T11:33:56.000Z</n0:StartDateTime>
  </crossWayBill>
