使用DOM4J解析xml的一种常用的方式，用到了可以过来看看哦。
package com.test;//先加入dom4j.jar包 import java.util.HashMap;import java.util.Iterator;import java.util.Map;import org.dom4j.Document;import org.dom4j.DocumentException;import org.dom4j.DocumentHelper;import org.dom4j.Element;/** * @description 解析xml字符串 * @author nova * @Time 2012年9月16日11:25:08 */public class TestDOM4J {/** * @description 将xml字符串转换成map * @param xml * @return Map */public static Map readStringXmlOut(String xml) {Map map = new HashMap();Document doc = null;try {doc = DocumentHelper.parseText(xml); // 将字符串转为XMLElement rootElt = doc.getRootElement(); // 获取根节点System.out.println("根节点：" + rootElt.getName()); // 拿到根节点的名称Iterator iter = rootElt.elementIterator("head"); // 获取根节点下的子节点head// 遍历head节点while (iter.hasNext()) {Element recordEle = (Element) iter.next();String title = recordEle.elementTextTrim("title"); // 拿到head节点下的子节点title值System.out.println("title:" + title);map.put("title", title);Iterator iters = recordEle.elementIterator("script"); // 获取子节点head下的子节点script// 遍历Header节点下的Response节点while (iters.hasNext()) {Element itemEle = (Element) iters.next();String username = itemEle.elementTextTrim("username"); // 拿到head下的子节点script下的字节点username的值String password = itemEle.elementTextTrim("password");System.out.println("username:" + username);System.out.println("password:" + password);map.put("username", username);map.put("password", password);}}Iterator iterss = rootElt.elementIterator("body"); // /获取根节点下的子节点body// 遍历body节点while (iterss.hasNext()) {Element recordEless = (Element) iterss.next();String result = recordEless.elementTextTrim("result"); // 拿到body节点下的子节点result值System.out.println("result:" + result);Iterator itersElIterator = recordEless.elementIterator("form"); // 获取子节点body下的子节点form// 遍历Header节点下的Response节点while (itersElIterator.hasNext()) {Element itemEle = (Element) itersElIterator.next();String banlce = itemEle.elementTextTrim("banlce"); // 拿到body下的子节点form下的字节点banlce的值String subID = itemEle.elementTextTrim("subID");System.out.println("banlce:" + banlce);System.out.println("subID:" + subID);map.put("result", result);map.put("banlce", banlce);map.put("subID", subID);}}} catch (DocumentException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();}return map;}public static void main(String[] args) {      //测试入口// 下面是需要解析的xml字符串例子String xmlString = "<html>" + "<head>" + "<title>dom4j解析一个例子</title>"+ "<script>" + "<username>nova</username>"+ "<password>123456</password>" + "</script>" + "</head>"+ "<body>" + "<result>0</result>" + "<form>"+ "<banlce>1000</banlce>" + "<subID>36242519880716</subID>"+ "</form>" + "</body>" + "</html>";Map map = readStringXmlOut(xmlString);Iterator iters = map.keySet().iterator();while (iters.hasNext()) {String key = iters.next().toString(); // 拿到键String val = map.get(key).toString(); // 拿到值System.out.println(key + "=" + val);}}}
