xml 服务器获得后取得数值

public static String sendPost(String url,String params) {
//访问网络，url：地址  params：json信息即传入服务器信息，返回值result即ResponseInfo1 的xml
   OutputStreamWriter  out = null;

//ResponseInfo1来源以上的sendPost函数

String ResponseInfo1 = <?xml version="1.0" encoding="UTF-8" standalone="yes"?><ats><code>99</code><message>版本不一致</message></ats>

String ResponseInfo2  = ParseXML(ResponseInfo1,"<message>","</message>");  // = 版本不一致
public static String ParseXML(String src,String key1,String key2){
   if(src == null || key1 == null || key2 == null) {
      return null;
   }
   
   String result = "";
   int begin = src.indexOf(key1);
   if(begin != -1) {
      result = src.substring(begin +key1.length());
   }
   int end = result.indexOf(key2);
   if(end != -1) {
      result = result.substring(0,end);
   }
   
   return result;
}
打印 
ResponseInfo2  版本不一致
