JDOM操作

用JAVA实现对xml文件的读写操作
1：导入JDOM包
2：实现对xml文件的写入和读取

package com.viita;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.List;

import org.jdom.Document;
import org.jdom.Element;
import org.jdom.JDOMException;
import org.jdom.input.SAXBuilder;
import org.jdom.output.Format;
import org.jdom.output.XMLOutputter;

public class TestJdom<E> {
    
    //读取xml文件

    public void read() throws Exception {
        // TODO Auto-generated method stub

        SAXBuilder sd = new SAXBuilder();
        Document doc = sd.build("c:/db.xml");
        Element root = doc.getRootElement();
        System.out.println(root.getChild("branch").getValue()); //读取指定节点名称的值

        
        //循环读取所有节点信息

         List<Element> list = root.getChildren();
         for (Element element : list) {
            System.out.println(element.getName()+" "+element.getValue());
        }

    }
    
    //写入xml文件

    public void write() throws Exception {
        // TODO Auto-generated method stub

        Document doc = new Document();
        Element root = new Element("root"); //添加节点

        
        Element leafage = new Element("leafage");
        leafage.setText("left"); //给节点赋值

        
        Element branch = new Element("branch");
        branch.setText("right"); //给节点赋值

        
        root.addContent(leafage);
        root.addContent(branch); //子结点与根节点进行关联

        
        doc.setRootElement(root);//确定根节点

        
        //输出

        XMLOutputter out = new XMLOutputter();
        Format format = Format.getPrettyFormat();
        out.setFormat(format);
        out.output(doc,new FileOutputStream("c:/db.xml"));
//        out.output(doc,System.out);

        


    }
    
    public static void main(String[] args) throws Exception {
        TestJdom<Integer> jdm = new TestJdom<Integer>();
        jdm.read();
//        jdm.write();

    }
    public void setdoX(E e)
    {
        
    }
    

}
