Jdom方式创建/解析xml

1.新建文件名为：Jdomdemo.java，代码：

package com.test;
 
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Iterator;
import java.util.List;
 
import org.jdom.Attribute;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.JDOMException;
import org.jdom.input.SAXBuilder;
import org.jdom.output.XMLOutputter;
 
import com.inter.XmlDocument;
 
public class JDomDemo implements XmlDocument
{
 
    public void createXml(String fileName)
    {
        Document document;  
        Element  root;  
        root=new Element("employees");  
        document=new Document(root);  
        Element employee=new Element("employee");  
        root.addContent(employee);  
        Element name=new Element("name");  
        name.setText("ddvip");  
        employee.addContent(name);  
        Element sex=new Element("sex");  
        sex.setText("m");  
        employee.addContent(sex);  
        Element age=new Element("age");  
        age.setText("23");  
        employee.addContent(age);  
        XMLOutputter XMLOut = new XMLOutputter();  
        try {  
            XMLOut.output(document, new FileOutputStream(fileName));  
            } catch (FileNotFoundException e) { 
                e.printStackTrace();  
                } catch (IOException e) { 
                    e.printStackTrace();  
                    }  
    }
 
    public void parserXml(String fileName)
    {
        SAXBuilder sax = new SAXBuilder();
        try {
         Document xmlDom = sax.build(new File(fileName));
         Element root = xmlDom.getRootElement();
         System.out.println(root.getName());
         List childList = root.getChildren();
         Iterator listIt = childList.iterator();
         while(listIt.hasNext()){
          Element element = (Element)listIt.next();
          System.out.println(element.getName());
         }
         Element firstChild = (Element) childList.get(0);
         List attrList = firstChild.getAttributes();
         Iterator attrIt = attrList.iterator();
         while(attrIt.hasNext()){
          Attribute  attr = (Attribute ) attrIt.next();
          System.out.println(attr.getName());
          System.out.println(attr.getValue());
          System.out.println(attr.getAttributeType());
         }
         List sonList = firstChild.getChildren();
         Iterator sonIt = sonList.iterator();
         while(sonIt.hasNext()){
          Element temp = (Element)sonIt.next();
          System.out.println(temp.getName()+"："+temp.getValue());
         }
        } catch (JDOMException e) {
         e.printStackTrace();
        } catch (IOException e) {
         e.printStackTrace();
        }
        System.out.println("----jdom 解析完毕-----");
    }
 
}

2.编写测试类，TestJdom.java，代码如下：

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