test.xml

  <disk name="C">
    <capacity>8G</capacity>
    <directories>200</directories>
    <files>1580</files>

  <disk name="D">
    <capacity>10G</capacity>

TestXml.java

import java.io.IOException;
import java.util.*;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.JDOMException;
import org.jdom.input.SAXBuilder;

public class TestXml {

    public TestXml() throws JDOMException, IOException, InstantiationException,
            IllegalAccessException, ClassNotFoundException {
        SAXBuilder sb = new SAXBuilder();
        Document doc = sb.build(TestXml.class.getClassLoader()
                .getResourceAsStream("test.xml")); // 构造文档对象

        Element root = doc.getRootElement(); // 获取根元素HD
        List list = root.getChildren("disk");

        for (int i = 0; i < list.size(); i++) {
            Element element = (Element) list.get(i);
            String capacity = element.getChildText("capacity");
            String directories = element.getChildText("directories");
            String files = element.getChildText("files");

            System.out.println(element.getAttributeValue("name") + ":");
            System.out.println("capacity:" + capacity + "
" + "directories:"
                    + directories + "
" + "files:" + files
                    + "
----------------------------------------");

        }

    }

    public static void main(String arg[]) {
        try {
            TestXml s = new TestXml();

        } catch (Exception e) {
        }
    }

}

测试结果：

C:
capacity:8G
directories:200
files:1580
----------------------------------------
D:
capacity:10G
directories:500
files:3000
