这篇文章主要介绍了Java使用Jdom读取xml解析,以实例形式较为详细的分析了Jdom操作XML文件实现读取操作的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了Java使用Jdom读取xml解析。分享给大家供大家参考，具体如下：

				?

									package com.yanek.demo.xml.test;

									import java.io.File;

									import java.io.IOException;

									import java.util.Iterator;

									import java.util.List;

									import org.jdom.Document;

									import org.jdom.Element;

									import org.jdom.JDOMException;

									import org.jdom.input.SAXBuilder;

									public class JdomReadXml {

									 /**

									 * @param args

									 */

									 public static void main(String[] args) {

									 /**

									  * <?xml version="1.0" encoding="UTF-8"?> <actions m="001"><action

									  * path="/test" class="com.mystruts.demo.LoginAction"><forward

									  * name="success" url="test.jsp" /><forward name="failure"

									  * url="failure.jsp" /></action><action path="/user"

									  * class="com.mystruts.demo.UserAction"><forward name="success"

									  * url="test.jsp" /><forward name="failure" url="failure.jsp" /></action></actions>

									  */

									 SAXBuilder sax = new SAXBuilder();

									 Document doc;

									 try {

									  try {

									  doc = sax.build(new File("mystruts.xml"));

									  Element root = doc.getRootElement();

									  List actions = root.getChildren();

									  // 遍历获取根节点下的一级子节点，并作为入参传入递归方法

									  for (Iterator i = actions.iterator(); i.hasNext();) {

									   Element action = (Element) i.next();

									   System.out.println(action.getAttributeValue("path"));

									   System.out.println(action.getAttributeValue("class"));

									   List forwards = action.getChildren();

									   for (Iterator j = forwards.iterator(); j.hasNext();) {

									   Element forward = (Element) j.next();

									   System.out.println(forward.getAttributeValue("name"));

									   System.out.println(forward.getAttributeValue("url"));

									   }

									  }

									  } catch (IOException e) {

									  // TODO Auto-generated catch block

									  e.printStackTrace();

									  }

									 } catch (JDOMException e) {

									  e.printStackTrace();

									 }

									 }

									}

输出：

				?

									/test

									com.mystruts.demo.LoginAction

									success

									test.jsp

									failure

									failure.jsp

									/user

									com.mystruts.demo.UserAction

									success

									test.jsp

									failure

									failure.jsp
