Dom4J方式创建/解析xml
1.新建文件名为：Dom4jdemo.java，代码：
?
package com.test; 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.inter.XmlDocument; public class Dom4jDemo implements XmlDocument{ //创建xml 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("ddvip"); 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()); } } //解析xml 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 i = employees.elementIterator(); i.hasNext();){ Element employee = (Element) i.next(); for(Iterator 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 解析完毕--------"); } }??

2.编写测试类，TestDom4j.java，代码如下：
?

?
public class TestDom{ public static void main(String[] args) {Dom4jdemo dom4j= new Dom4jdemo(); //创建的xml见图一dom4j.createXml("D://employee.xml");//解析的xml见图二dom4j.parseXml("E://employee.xml"); }}?
