　　2.解析xml数据

private JSONObject parseXML(String Data, String returnType) {

JSONObject jsonObject = null;

if ("xml".equals(returnType)) {
       org.dom4j.Document document = DocumentHelper.parseText(buffer.toString());     List
     
       list = document.getRootElement().elements();     jsonObject = new JSONObject();     for (int i = 0; i < list.size(); i++) {
           jsonObject.put(list.get(i).getName(), list.get(i).getData());     } } else {
       jsonObject = JSONObject.parseObject(buffer.toString()); } return jsonObject;
     

}
