### 1.1java源码 ###

package com.heima.test;
    
    import java.io.File;
    import java.util.List;
    
    import org.dom4j.Document;
    import org.dom4j.Element;
    import org.dom4j.io.SAXReader;
    /* * dom4j的标准解析xml文件 */
    public class test { 
    	public static void main(String[] args) { 
    		try { 
    		//创建对象
    			SAXReader reader = new SAXReader();
    		//确定解析源
    			Document document = reader.read(new File("src/xml/demo.xml"));
    			
    		//获取根元素
    			Element rootElement = document.getRootElement();
    			
    // System.out.println(rootElement.element("stu").element("age").getText());
    		//将所有元素存在List中
    			List<Element> elements = rootElement.elements();
    			for (Element element : elements) { //遍历List
    // System.out.println(element);
    				
    				String name = element.element("name").getText();
    				String age = element.element("age").getText();
    				System.out.println("name = " + name + " :age = " + age);
    				
    			}
    			
    			
    		} catch (Exception e) { 
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
    	}
    }

    		<name>cds</name>
    		<age>18</age>
    	</stu>
    	
    	<stu id="03164048">
