使用Jdom进行简单的XML解析

使用Jdom进行简单的XML解析

1、引入相应的Jar包
jdom-2.0.4.jar 下载地址：http://www.jdom.org/downloads/index.html
2、准备一个简单的Xml文件

<?xml version="1.0" encoding="UTF-8"?>
<prop>
    <property name="sSize" value="52"></property>
    <property name="cSize" value="23"></property>
    <property name="pSize" value="15"></property>
    <property name="aSize" value="25"></property>
</prop>

3、编写进行解析XML文件的测试程序

import java.io.IOException;
import java.util.List;
import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.JDOMException;
import org.jdom2.input.SAXBuilder;

public class TestJdomReader {

	public static void main(String[] args) {
		//创建一个SAXBuilder对象
		SAXBuilder sax = new SAXBuilder();
		
		try {
			//根据文件创建一个Document对象 
			Document doc = sax.build("test.xml");
			
			//获取根结点
			Element root = doc.getRootElement();
			
			//获取所有根结点
			List<Element> children = root.getChildren();
			
			//遍历所有结点，并列出相应的属性值
			for(int i = 0; i < children.size(); i++) {
				Element child = children.get(i);
				
				//拿到结点名称
				System.out.print(child.getName() + ": ");
				//拿到结点中属性名为name的属性值
				System.out.print("name = " + child.getAttributeValue("name") + ", ");
				System.out.println("value = " + child.getAttributeValue("value"));
			}
			
		} catch (JDOMException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

4、程序运行结果
property: name = sSize, value = 52
property: name = cSize, value = 23
property: name = pSize, value = 15
property: name = aSize, value = 25
