</dependency>

Using Document.getAllElements() method

Following Java code example using getAllElements() method in jsoup library to find all Elements from a HTML document.

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

public class GetAllElementsExample1 {
    public static void main(String... args) {
        String htmlContent = "<!DOCTYPE html>" +
                "<html>" +
                "<body>" +
                "<h1>Simple Solution</h1>" +
                "</body>" +
                "</html>";

        Document document = Jsoup.parse(htmlContent);

        Elements elements = document.getAllElements();

        for (Element element : elements) {
            System.out.println(element.tagName());
        }
    }
}
Output:
#root
html
head
body
h1

Using Document.select() method

We also can use select() method with CSS query “*” to find all elements.

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

public class GetAllElementsExample2 {
    public static void main(String... args) {
        String htmlContent = "<!DOCTYPE html>" +
                "<html>" +
                "<body>" +
                "<h1>Simple Solution</h1>" +
                "</body>" +
                "</html>";

        Document document = Jsoup.parse(htmlContent);

        Elements elements = document.select("*");

        for (Element element : elements) {
            System.out.println(element.tagName());
        }
    }
}
Output:
#root
html
head
body
h1
