01_1_jdom调用xml文件
1. 导入jdom.jar包
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
------------------
