DOM4J解析xml最简单例子

package 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;

 

public class dom4j {

    public static void main(String[] args) {

            //creatXML();拼xml

            //parserXML();解析xml

    }

    /**

     * 拼XML

     */

    public static void creatXML(){

        Document document = DocumentHelper.createDocument();

        Element elements = document.addElement("elements");

        Element element = elements.addElement("element");

        Element name = element.addElement("name");

        name.setText("myname");

        Element sex = element.addElement("sex");

        sex.setText("man");

         

        try {

            Writer fwriter =new FileWriter("xmlText.xml");

            XMLWriter xwriter =new XMLWriter(fwriter);

            xwriter.write(document);

            xwriter.close();

        } catch(IOException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

    }

    /**

     * 解析XML

     */

    public static void parserXML(){

        File file = new File("xmlText.xml");

        SAXReader saxReader =new SAXReader();

        try {

            Document document = saxReader.read(file);

            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) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

    }

     

}

java实现,唯一前提是先下载个dom4j的jar包。
