存储数据

Question

我想MongoDB中插入数据（XML文件的内容）：

ArrayList<Object> map = new ArrayList<Object>(); 
      try 
      { 

       File file = new File ("test.xml"); 
       InputStream inputStream = new FileInputStream(file); 
       StringBuilder builder = new StringBuilder(); 
       int ptr = 0; 
       while ((ptr = inputStream.read()) != -1) 

        { 
         builder.append((char) ptr); 

        } 

       String xml = builder.toString(); 
       inputStream.close(); 
       org.json.JSONArray jsonarray = JSONML.toJSONArray(xml); 

       // jsonArray to map 
       map= toList(jsonarray); 
       DB db = (new MongoClient("localhost",27017)).getDB("test"); 

       //get a single collection 
       DBCollection dbcollection = db.getCollection("mycoll"); 



      //insert the list of object in mongodb ? ? ? 

，但我不知道如何从对象（JSON）的列表中插入mongodb？ 是否有任何其他方式从XML提取数据，并将其（保持XML文件的结构，wihtout解析文件）存储在蒙戈

 //After Getting collection , you can insert the document. Here is the code snippet. 




BasicDBObject document = new BasicDBObject(); 
     document.put("a", "b"); 
     document.put("c", "d"); 

     BasicDBObject documentDetail = new BasicDBObject(); 
     documentDetail.put("e", new ArrayList<String>()); 

     document.put("xyz", documentDetail); 

     collection.insert(document);
