android调用webservice

asp.net的后台，直接返回了datatable,内容如下：<?xml version="1.0" encoding="UTF-8"?>

andro Code如下: if(envelope.getResponse() != null){
                SoapObject result2 =(SoapObject)envelope.getResponse();
               String strTv2="获得数组：";
               for(int i=0;i<result2.getPropertyCount();i++)
               {
                 SoapObject soapChilds =(SoapObject)result2.getProperty(i); 
                 strTv2 +=soapChilds.getProperty("ArtiCode").toString();
             }
以上代码获得此错误“illegal property: ArtiCode”；SoapObject result2 =(SoapObject)envelope.getResponse();result2从服务器返回数据如下：
目的是在strTv2中循环获得节点字符，然后显示在TextView中，但是我的结果如上图。求教各位高手，如何获得此XML中的数据，求助!!!感激
