String responseBody= "<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body>

       </DisplayCashTransactionForPayingResponse>
      </s:Body>
              </s:Envelope>"

我想获取节点的值（sendercity、sendermiddlename、sendcountrycode..和所有剩余的字段值），但soap响应正文显示为null，我的代码为

MimeHeaders header = new MimeHeaders();     
           header.addHeader("Content-Type", "text/xml");

            MessageFactory factory = MessageFactory.newInstance();
         InputStream is = new ByteArrayInputStream(responseBody.getBytes());
         SOAPMessage soapMessage = factory.createMessage(header,is);

        SOAPBody body = soapMessage.getSOAPBody();
        NodeList nodes = body.getElementsByTagName("DisplayCashTransactionForPayingResult");
        System.out.println("jjjjjjjjjjjjjj"+nodes.toString());
        // check if the node jjjjjjjjjjjjjjexists and get the value
        String someMsgContent = null;

但结果为空..请帮助获取节点元素和值。请帮忙
