HASHMAP里面数据封装成XML

public static String getGridStrByMap(Map hashMap){
   
   if(hashMap.isEmpty()){
    return "";
   }
   
   StringBuffer strBuffer = new StringBuffer();
   Iterator it = hashMap.keySet().iterator();
   
   while (it.hasNext()){
    String key = (String) it.next();
    Object value = hashMap.get(key);
    strBuffer.append("<" + key + "><![CDATA[" + (value == null ? "" : value) + "]]></" + key + ">\n");
   }
   
   return strBuffer.toString();
  }
