java中四种操作（DOM、SAX、JDOM、DOM4J ... | XML字符串和XML DOCUMENT的相互转换

2008-03-12

JDOM读写XML文件

关键字: jdom

package com.test;
import org.jdom.;
import org.jdom.input.;
import org.jdom.output.*;

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

public class MyJDom {

    public static void main(String[] args) throws Exception{
        SAXBuilder sb=new SAXBuilder();//建立构造器
        Document doc=sb.build(new FileInputStream("src/xml/abc.xml"));//读入指定文件

Element root=doc.getRootElement();//获得根节点
List list=root.getChildren();//将根节点下的所有子节点放入List中

for(int i=0;i<list.size();i++) {

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

Element item=(Element)list.get(i);//取得节点实例

String id=item.getAttribute("id").getValue();//取得属性值

System.out.println("id-->"+id);

Element sub=item.getChild("title");//取得当前节点的字节点
String text=sub.getText();//取得当前节点的值

System.out.println("Title-->"+text);

            if(item.getChild("content").getChildren().size()>0){
            Element sub2=item.getChild("content").getChild("name");
                String text2=sub2.getText();

                System.out.println("name-->"+text2);
            }

Element sub3=item.getChild("email");
String text3=sub3.getText();

            System.out.println("Email-->"+text3);
        }
      }
}

附：要读取的xml文件如下：abc.xml

<?xml version="1.0" encoding="gb2312"?>
<messages>
<message id="1">
   <title>11</title>
   <content>
    <name>lvpingyu</name>
    <age>23</age>
   </content>
   <email>33</email>
</message>
<message id="2">
   <title>44</title>
   <content>
    <name>lvpingyu</name>
    <age>23</age>
   </content>
   <email>66</email>
</message>
</messages>
