01_1_jdom调用xml文件

01_1_jdom调用xml文件

1. 导入jdom.jar

2. xml文件内容

test.xml

<?xml version="1.0" encoding="UTF-8"?>

<HD>

  <disk name="C">

    <capacity>8G</capacity>

    <directories>200</directories>

    <files>1580</files>

  </disk>

 

  <disk name="D">

    <capacity>10G</capacity>

    <directories>500</directories>

    <files>3000</files>

  </disk>

</HD> 

 

 

 

3.实现类

 

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;

 

 

public class Sample1 {

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

SAXBuilder sb = new SAXBuilder();

Document doc = sb.build(Sample1.class.getClassLoader().getResourceAsStream("test.xml")); //构造文档对象

Element root = doc.getRootElement(); //获取根元素

List list = root.getChildren("disk");//取名字为disk的所有元素

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

Element element = (Element) list.get(i);

String name = element.getAttributeValue("name");

String capacity = element.getChildText("capacity");//获取disk元素capacity的值

String directories = element.getChildText("directories");

String files = element.getChildText("files");

System.out.println("磁盘信息:");

System.out.println("分区盘符:" + name);

System.out.println("分区容量:" + capacity);

System.out.println("目录数:" + directories);

System.out.println("文件数:" + files);

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

}

}

}

 

 

 

4.运行结果

磁盘信息:

分区盘符:C

分区容量:8G

目录数:200

文件数:1580

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

磁盘信息:

分区盘符:D

分区容量:10G

目录数:500

文件数:3000

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