完全理解，比网上其他资料都要详细类 XMLSerializer
java.lang.Object
net.sf.json.xml.XMLSerializer
public class XMLSerializer
extends java.lang.Object
Utility class for transforming JSON to XML an back.
When transforming JSONObject and JSONArray instances to XML, this class will
add hints for converting back to JSON.
JSONObject json = JSONObject.fromObject("{\"name\":\"json\",\"bool\":true,\"int\":1}");
String xml = new XMLSerializer().write( json );
JSONArray json = JSONArray.fromObject("[1,2,3]");
String xml = new XMLSerializer().write( json );
