jdom的运用

1.到官网下载jdom文件。（www。jdom.org）

2.减压缩：找到build下的jdom包 。

web中使用：直接拷贝到Tomcat目录放在lib文件夹下即可。

程序中使用：找到jdom.jar的路径，复制到CLASSPATH环境中去。

import java.io.*;
import org.jdom.*;
import org.jdom.output.*;
public class WriteXML {
    public static void main(String[] args) throws Exception {
        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","lop");
        Document doc = new Document (addresslist);
        name.setText("lcp");
        name.setAttribute(id);//讲属性设置到元素之中
        email.setText("mldn@l63.com");
        linkman.addContent(name);//设置关系
        linkman.addContent(email);
        addresslist.addContent(linkman);
        XMLOutPutter out = new XMLOutPutter();
        out.setFormat(out getFormat(),setEncoding("GBK"));
        out.output(doc,new FileOutputStream(new File("D:" + File.separator + "address.xml")));
    }
}

sax 解析文件

public class WriteXML {
    public static void main(String args[]) throws Exception{
        SAXBuilder builder = new SAXBuilder();
        Document read_doc = builder.build(new File("D:" + File.separator + "address.xml"));
        Element root = read_doc.getRootElement();//取得根
        List list = root.getChildree("linkman");//取得所有的linkman
        for(int x = 0; x < list.size(); x++){
            Element e = (Element)list.get();
            String name = e.getChildText("name");//得到name子节点内容
            String id = e.getChild("name").getAttribute("id").getValue(); 
            String email = e.getChildText("email");
            System.out.println("姓名" + name + ",编号" + id );
            System.out.println("Eamil" + name + " );
        }
    }
