使用dom4j解析xml文件

Stu.java

    private String name;
    private int age;
    private String sex;

    public Stu(String name, int age, String sex) {
        this.name = name;
        this.age = age;
        this.sex = sex;
    }

    public Stu() {
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    @Override
    public String toString() {
        return "Stu{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", sex='" + sex + '\'' +
                '}';
    }
}

student.xml

<?xml version="1.0" encoding="utf-8"?>
<students>
    <student>
        <name>张三</name>
        <age>18</age>
        <sex>男</sex>
    </student>
    <student>
        <name>李四</name>
        <age>19</age>
        <sex>女</sex>
    </student>
</students>

getxml.java

import Bean.Stu;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
import org.junit.Test;
import java.util.List;

public class getxml {
    @Test
    public void get() throws Exception {
        //获取SAXReader对象
        SAXReader saxReader = new SAXReader();
        //读取配置文件
        Document read = saxReader.read("./src/main/java/src/student.xml");
        //获取根标签
        Element rootElement = read.getRootElement();
        //根据根标签获取”student“标签列表
        List<Element> students = rootElement.elements("student");
        //遍历
        for (Element student : students){
            //获取标签的文本
            String name = student.elementText("name");
            int age = Integer.parseInt(student.elementText("age"));
            String sex = student.elementText("sex");
            Stu stu = new Stu(name, age, sex);
            System.out.println(stu);
        }

    }
}

结果：
