XmlToJson转换

JAVA代码如下：

package com.tony;

import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;
import java.util.LinkedList;
import java.util.List;
import java.util.Map;

import net.sf.json.JSONObject;

import org.apache.commons.io.FileUtils;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.input.SAXBuilder;

public class XmlToJson {

	public static void main(String[] args) {
		String xmlStr = null;
		try {
			xmlStr = FileUtils.readFileToString(new File(new XmlToJson().getClass().getClassLoader().getResource(".").getPath() + "data.xml"));
			String jsonStr = xmlToJson(xmlStr);
			System.out.println(jsonStr);
		} catch (IOException e) {
			e.printStackTrace();
		}

	}

	public static String xmlToJson(String xml) {
		JSONObject obj = new JSONObject();
		try {
			InputStream is = new ByteArrayInputStream(xml.getBytes("UTF-8"));
			SAXBuilder sb = new SAXBuilder();
			Document doc = sb.build(is);
			Element root = doc.getRootElement();
			obj.put(root.getName(), iterateElement(root));
			return obj.toString();
		} catch (Exception e) {
			e.printStackTrace();
			return null;
		}
	}

	private static Map iterateElement(Element element) {
		List jiedian = element.getChildren();
		Element et = null;
		Map obj = new HashMap();
		List list = new LinkedList();
		int num = 0;
		for (int i = 0; i < jiedian.size(); i++) {
			et = (Element) jiedian.get(i);
			if (et.getTextTrim().equals("")) {
				if (et.getChildren().size() == 0)
					continue;
				if (obj.containsKey(et.getName())) {
					++num;
					if (num == 1)
						list.add(obj.get(et.getName()));
					list.add(iterateElement(et));
					obj.put(et.getName(), list);
				} else {
					obj.put(et.getName(), iterateElement(et));
				}
			} else {
				obj.put(et.getName(), et.getTextTrim());
			}
		}
		return obj;
	}

}

xml文档内容如下：

转换结果：
