一个使用org.json的Demo：
1 import org.apache.commons.io.IOUtils;
2 import org.json.JSONException;
3 import org.json.JSONObject;
4 import org.json.XML;
5
6 import java.io.IOException;
7 import java.io.InputStream;
8
9 public class XML2JSON {
10
11 public XML2JSON(){}
12
13 public static String xml2jsonString(String filepath) throws IOException, JSONException {
14
15 InputStream in = XML2JSON.class.getResourceAsStream(filepath);
16 String xml = IOUtils.toString(in);
17 System.out.print(xml);
18 System.out.println();
19
20 JSONObject xmlJSONObj = XML.toJSONObject(xml);
21 String jsonStr = xmlJSONObj.toString();
22 System.out.print(jsonStr);
23
24 return xmlJSONObj.toString();
25
26 }
27
28
29 public static void main(String[] args) throws JSONException, IOException {
30
31 String string = xml2jsonString("simple.xml");
32 System.out.println(string);
33
34 }
35
36 }

各路方法，有使用第三方API，或者自写遍历迭代方法。
在针对上述Demo的测试结果做分析，还需要进一步考虑以下几点：
1. 源XML文件自身特殊及复杂情况的转换定义。比如，字段含特殊字符，一个标签含多个属性，多个标签同名，invalid file等。
2. 目标JSON文件的转换定义。比如，各元素是否保持原有顺序，多个同名标签作为数组还是同级对象，等。
3. 转换过程中的异常处理。比如，转换中遇到无法解析而跳出导致该目标文件无效，异常捕获记录，等。
