java解析xml四种方式(3)-dom4j方式

DOM4J 是一个非常非常优秀的Java XML API，具有性能优异、功能强大和极端易用使用的特点，同时它也是一个开放源代码的软件。如今你可以看到越来越多的 Java 软件都在使用 DOM4J 来读写 XML，特别值得一提的是连 Sun 的 JAXM 也在用 DOM4J。

package com.michael.xml.dom4j;import java.io.File;import java.io.FileWriter;import java.io.IOException;import java.io.Writer;import java.util.Iterator;import org.dom4j.Document;import org.dom4j.DocumentException;import org.dom4j.DocumentHelper;import org.dom4j.Element;import org.dom4j.io.SAXReader;import org.dom4j.io.XMLWriter;import com.michael.xml.dom.XmlDocument;/** * @author michael 生成XML文档与解析XML文档 *  */public class Dom4jDemo implements XmlDocument {public void createXml(String fileName) {Document document = DocumentHelper.createDocument();Element employees = document.addElement("employees");Element employee = employees.addElement("employee");Element name = employee.addElement("name");name.setText("michael");Element sex = employee.addElement("sex");sex.setText("m");Element age = employee.addElement("age");age.setText("29");try {Writer fileWriter = new FileWriter(fileName);XMLWriter xmlWriter = new XMLWriter(fileWriter);xmlWriter.write(document);xmlWriter.close();} catch (IOException e) {System.out.println(e.getMessage());}}public void parserXml(String fileName) {File inputXml = new File(fileName);SAXReader saxReader = new SAXReader();try {Document document = saxReader.read(inputXml);Element employees = document.getRootElement();for (Iterator<Element> i = employees.elementIterator(); i.hasNext();) {Element employee = (Element) i.next();for (Iterator<Element> j = employee.elementIterator(); j.hasNext();) {Element node = (Element) j.next();System.out.println(node.getName() + ":" + node.getText());}}} catch (DocumentException e) {System.out.println(e.getMessage());}System.out.println("dom4j parserXml");}public static void main(String[] args) {Dom4jDemo demo = new Dom4jDemo();// demo.createXml("d:/michael_dom4j.xml");demo.parserXml("d:/michael.xml");}}

注意：以上代码依赖dom4j.jar
