无法在android / eclipse上使用Web服务的值

Question

现在我在android / eclipse上使用SOAP Web服务。它的工作正常。请找到我的服务链接

“http://54.251.60.177/MobileWS/Student.asmx?wsdl”

“GetStudentInformation”，这是我正在使用的服务，其输入值为“111105009”

如果我将此值作为上述服务的输入，它只是在模拟器上显示结果，如下图所示，并公开显示这些内容。

IMAGE_1

IMAGE_2

但是我的问题是，上面的image_2显示了所有带有答案的xml标签，但我只需要显示我在image_2上提到的答案。如何实现这个概念？

请在下方找到我的来源

WebMethod.java

public class GetStudentInformation 
{
public String GetStudentInformation(String sStudentCode)
{
    return sStudentCode;

         //Initialize soap request + add parameters
         SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

         //Use this to add parameters

         request.addProperty("sStudentCode",txtFar.getText().toString());

         //Declare the version of the SOAP request

         SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

             //this is the actual part that will call the webservice

             androidHttpTransport.call(SOAP_ACTION, envelope);

             // Get the SoapResult from the envelope body.

             SoapPrimitive result = (SoapPrimitive)envelope.getResponse();


             if (result != null)
             {
