java xml与json互转

xml和json互转，这里给一些示例

https://github.com/smart-fun/XmlToJson

xml转json

String xmlString;  // some XML String previously created
XmlToJson xmlToJson = new XmlToJson.Builder(xmlString).build();

// convert to a JSONObject
JSONObject jsonObject = xmlToJson.toJson();

// convert to a Json String
String jsonString = xmlToJson.toString();

// convert to a formatted Json String
String formatted = xmlToJson.toFormattedString();

原xml

<?xml version="1.0" encoding="utf-8"?>
<library>
    <owner>John Doe</owner>
    <book id="007">James Bond</book>
    <book id="000">Book for the dummies</book>
</library>

转换后

{  
   "library":{
      "owner": "John Doe",
      "book":[  
         {  
            "id":"007",
            "content":"James Bond"
         },
         {  
            "id":"000",
            "content":"Book for the dummies"
         }
      ]
   }
}

反之json转xml

JSONObject jsonObject; // some JSONObject previously created
JsonToXml jsonToXml = new JsonToXml.Builder(jsonObject).build();

// Converts to a simple XML String
String xmlString = jsonToXml.toString();

// Converts to a formatted XML String
int indentationSize = 3;
String formattedXml = jsonToXml.toFormattedString(indentationSize);

还有一些自定义名称和属性，大家可以看开源文档。
