jsoup - Using DOM Methods

Following example will showcase use of DOM like methods after parsing an HTML String into a Document object.

Syntax

Document document = Jsoup.parse(html);
Element sampleDiv = document.getElementById("sampleDiv");
Elements links = sampleDiv.getElementsByTag("a");

Where

  • document − document object represents the HTML DOM.

  • Jsoup − main class to parse the given HTML String.

  • html − HTML String.

  • sampleDiv − Element object represent the html node element identified by id "sampleDiv".

  • links − Elements object represents the multiple node elements identified by tag "a".

Description

The parse(String html) method parses the input HTML into a new Document. This document object can be used to traverse and get details of the html dom.

Example

Create the following java program using any editor of your choice in say C:/> jsoup.

JsoupTester.java

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

public class JsoupTester {
   public static void main(String[] args) {
   
      String html = "<html><head><title>Sample Title</title></head>"
         + "<body>"
         + "<p>Sample Content</p>"
         + "<div id='sampleDiv'><a href='www.google.com'>Google</a></div>"
         +"</body></html>";
      Document document = Jsoup.parse(html);
      System.out.println(document.title());
      Elements paragraphs = document.getElementsByTag("p");
      for (Element paragraph : paragraphs) {
         System.out.println(paragraph.text());
      }

      Element sampleDiv = document.getElementById("sampleDiv");
      System.out.println("Data: " + sampleDiv.text());
      Elements links = sampleDiv.getElementsByTag("a");

      for (Element link : links) {
         System.out.println("Href: " + link.attr("href"));
         System.out.println("Text: " + link.text());
      }
   }
}

Verify the result

Compile the class using javac compiler as follows:

C:\jsoup>javac JsoupTester.java

Now run the JsoupTester to see the result.

C:\jsoup>java JsoupTester

See the result.
