Is there a better way of parsing SoapObject in Android

So far I've managed to connect to a Web Service and get my SoapObject response, but I'm having trouble narrowing down a good, clean way of parsing. Searching the Internet hasn't really yielded much results, everyone has a different way and different process usually geared towards their own Web Service making it a one time use type of solution. Basically, below is the response that I get from a Web Service

anyType{
 schema=anyType{
  element=anyType{
   complexType=anyType{
    choice=anyType{
     element=anyType{
      complexType=anyType{
       sequence=anyType{
        element=anyType{}; 
           element=anyType{}; 
            element=anyType{}; 
              element=anyType{}; }; }; }; }; }; }; };   
      diffgram=anyType{
         NewDataSet=anyType{
          Rep_x0020_Information=anyType{
            Login=CorrectLogin; Password=InCorrectPass; }; }; }; }

And basically I want to be able to parse out just the two important fields (Login and Password). From what I read I tried just iterating through the SoapObject response based on the property count but that doesn't seem to work. When I tried I get a property count of 2 for the response so instead I ended up doing some thing like this below: 

SoapObject response=(SoapObject) envelope.getResponse();

                if  (response != null) {
                    Log.i("Message", "the response contains: " + response.toString());
                    SoapObject diffgram = (SoapObject) response.getProperty("diffgram");
                    SoapObject NewDataSet = (SoapObject) diffgram.getProperty("NewDataSet");
                    SoapObject RepInfo = (SoapObject) NewDataSet.getProperty("Rep_x0020_Information");
                    for (int i = 0; i < RepInfo.getPropertyCount(); i++) {
                        PropertyInfo info = new PropertyInfo();
                        RepInfo.getPropertyInfo(i, info);
                        Log.d("Info", info.name + " : " + RepInfo.getProperty(i).toString());
                    }


 //which gives the following message in LogCat
  D/Info(716): Login : InCorrectLogin
  D/Info(716): Password : InCorrectPass

This process works, as by the last loop I get the two objects I want but I just feel like there's a cleaner way of doing this. I only ask because as I get further into this App there will be some more complex Web Service calls being made and I want to be able to have something that is reusable throughout the app instead of having to build several SoapObjects for each request just to get down to the objects I want.

You can get the response (and request) xml in an easier way by setting the debug property in HttpTransportSE, and getting the requestDump and/or responseDump right after call. Something like this:

HttpTransportSE  httpTransport = new HttpTransportSE(wsURL);
httpTransport.debug = true;

httpTransport.call("WS_NAMESPACE" + methodName, envelope);

Log.w("RawXML Request:" + httpTransport.requestDump);
Log.w("RawXML Response:" + httpTransport.responseDump);

you can use it even in a try catch block, to analyze soap faults.

Dont forget to disable the debug after use, because it slow down the performance, in that case those Dump properties will be null.

There are 2 ways to parse object from web service:
First, assume you are a web service owner or creator, you can make web service return a Json string, then from client, you can create an entity map to Json, and Json library will take care parsing for you.

Second: web service usually response many complex objects, so you can make entities to map with these objects.
You can follow this tutorial to understand how to map a simple object, then go to my answer from this question to know parsing the complex object.
It's just something like this:

 HttpTransportSE androidHttpTransport = new HttpTransportSE(SERVER_URL);
 androidHttpTransport.call(SOAP_ACTION, envelope);// call
 Entity entity = (Entity)envelope.bodyIn;
