What to use to convert json to xml

This article will introduce two methods of converting json to xml. I hope it will be helpful to everyone.

The first method

Use the XML.toJSONObject(xml) method provided in XML.java to complete the xml to json conversion, you can also format JSON

/* 第一种方法，使用JSON-JAVA提供的方法 */  
       //将xml转为json  
       JSONObject xmlJSONObj = XML.toJSONObject(xml);  
       //设置缩进  
       String jsonPrettyPrintString = xmlJSONObj.toString(4);  
       //输出格式化后的json  
       System.out.println(jsonPrettyPrintString);

Second method

Use the XMLSerializer object of json-lib

 /* 第二种方法，使用json-lib提供的方法 */  
 //创建 XMLSerializer对象  
 XMLSerializer xmlSerializer = new XMLSerializer();  
 //将xml转为json（注：如果是元素的属性，会在json里的key前加一个@标识）  
 String result = xmlSerializer.read(xml).toString();  
 //输出json内容  
 System.out.println(result);

Note:When converting xml to json through json-lib, empty nodes will be converted into empty arrays, that is, [], which is very bad, so you need to convert [] into an empty string: jsonStr. replace("[]", "\"\"")
