wso2 API manager 1.9中JSON响应的xslt转换

我有一个这样格式的后端响应json示例：
我想从RESPONSEs和RESPONSE_ORDER标记中提取逗号分隔的值，以便在输出JSON中清楚地设置它们。本质上，我的输出应该是类似于使用xslt转换的输出。 使用xslt mediator，我希望将其转换如下：

{
  "d": {
    "results": [      
      {        
        "TYPE_ID": "20",
        "QUESTION_ID": "41333",
        "RESPONSE_TYPE": "Checkboxes",
        "QUESTIONVAL": "xssdsdd",
        "RESPONSE": "Yes",
        "RESPONSE_ORDER": "1"        
      }, 
      {        
        "TYPE_ID": "21",
        "QUESTION_ID": "417",
        "RESPONSE_TYPE": "Radio buttons",
        "QUESTIONVAL": "abc",
        "RESPONSE": "Yes,No",
        "RESPONSE_ORDER": "1,2"       
      }
    ]
  }
}

转换后的样本输出

{
    "results": [      
      {        
        "TYPE_ID": "20",
        "QUESTION_ID": "41333",
        "RESPONSE_TYPE": "Checkboxes",
        "QUESTIONVAL": "xssdsdd",
        Response&Order: [
            {
            "RESPONSE": "Yes",
            "RESPONSE_ORDER": "1"
            }
        ]               
      }, 
      {        
        "TYPE_ID": "21",
        "QUESTION_ID": "417",
        "RESPONSE_TYPE": "Radio buttons",
        "QUESTIONVAL": "abc",
        Response&Order: [
            {
            "RESPONSE": "Yes",
            "RESPONSE_ORDER": "1"
            },
            {
            "RESPONSE": "No",
            "RESPONSE_ORDER": "2"
            }
        ]             
      }
    ]
}

如何分割值以生成此类输出
