具有多个记录的JSON到XML

Question

我是JAVA的新手，并尝试将JSON数据格式转换为XML以获取多个记录。结果不是一个定义良好的XML结构。当存在一个项目记录时，下面的代码工作正常。

{
    "items": [
        {
            "item": {
                "ID": "79C675F752491945E1A",
                "Subject": "test1 ",
                "Sender": "user1",
                "Date": "2014-07-14 14:14:40",
                "DocumentClassID": "1",
                "Comment": "",                
            }
        },

        {
            "item": {
                "ID": "79C67761945E1A",
                "Subject": "test2",
                "Sender": "user2",
                "Date": "2014-07-14 14:14:40",
                "DocumentClassID": "1",
                "Comment": "",

            }
        }

    ]
}

=================== Code Snippet ========================== ===

public class ConvJsonXml extends AbstractTransformation {

    public void transform(TransformationInput in, TransformationOutput out) throws StreamTransformationException {

          try {
          String sourcexml = ""; String targetxml =""; String line ="";

          InputStream ins = in.getInputPayload().getInputStream();
          BufferedReader br = new BufferedReader( new InputStreamReader(ins));
          while ((line = br.readLine()) != null) 
          sourcexml +=line+"\n"; 
          br.close();

          JSONObject o = new JSONObject(sourcexml);
          targetxml = org.json.XML.toString(o);
          out.getOutputPayload().getOutputStream().write(targetxml.getBytes());

          }
            catch (Exception e) {
                   throw new StreamTransformationException(e.getMessage());
          }
        }

}

请建议我在Try块中添加代码，以便转换提供一个统一的XML结构。

此致..
