Jsoup的Document对象获取元素

形同js获取html中的标签元素

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

import java.io.File;
import java.io.IOException;

//Document对象获取元素
public class JsoupDemo3 {
    public static void main(String[] args) throws IOException {
        String path = JsoupDemo1.class.getClassLoader().getResource("student.xml").getPath();
        Document document = Jsoup.parse(new File(path),"utf-8");
        Elements elementsByAttributeValue = document.getElementsByAttributeValue("number", "heima_0001");
        System.out.println(elementsByAttributeValue.text());
        Element mouse = document.getElementById("mouse");
        System.out.println(mouse.text());
    }
}
