Jdom读写XML文件代码

首先下载jdom.jar。将其导入到你的项目中

JdomWriteXML.class

import java.io.File;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

import org.jdom.*;

import org.jdom.output.XMLOutputter;

public class JdomWriteXML {

public static void main(String[] args) throws FileNotFoundException, IOException {

Element addresslist  = new Element("addresslist");

Element linkman  = new Element("linkman");

Element name  = new Element("name");

Element email  = new Element("email");

Attribute id  = new Attribute("id", "flj");

Document doc = new Document(addresslist);//创建document对象

name.setText("fangleijiang");//给节点赋值

name.setAttribute(id);

email.setText("fangleijiang163.com");

linkman.addContent(name);//设置节点的关系

linkman.addContent(email);

addresslist.addContent(linkman);

XMLOutputter out  = new XMLOutputter();//文件输入对象

//创建文件

out.output(doc, new FileOutputStream(new File("WebRoot"+File.separator+"fangleijiang.xml")));

}

}

运行结果

在你指定的目录下面会生成你要的xml文件

这是我生成xml文件的内容

fangleijiangfangleijiang163.com

下面是解析xml文件代码

JdomReadXML.class

import java.io.File;

import java.io.IOException;

import java.util.*;

import org.jdom.*;

import org.jdom.input.SAXBuilder;

public class JdomReadXML {

public static void main(String[] args) throws JDOMException, IOException {

SAXBuilder builder = new SAXBuilder();

Document read_doc = builder.build(new File("WebRoot"+File.separator+"fangleijiang.xml"));

Element root = read_doc.getRootElement();//取得根节点

List list = root.getChildren("linkman");

for(int i = 0;i

Element e  = (Element) list.get(i);

String name = e.getChildText("name");

String id = e.getChild("name").getAttribute("id").getValue();

String email = e.getChildText("email");

System.out.println("------------联系人-------------");

System.out.println("name:"+name+",id："+id);

System.out.println("email:"+email);

System.out.println("------------------------------");

System.out.println();

}

}

}

运行结果

------------联系人-------------

name:fangleijiang,id：flj

email:fangleijiang163.com

------------------------------
