jsoup - Using DOM Methods



Overview

Jsoup.parse(file, string) parses the input HTML into a new Document. This document object can be used to traverse and get details of the html dom.

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".

Get an element by ID

Element sampleDiv = document.getElementById("sampleDiv");

Get elements by Tag

Elements links = sampleDiv.getElementsByTag("a");

Example - Parsing an html string and read Paragraphs

JsoupTester.java

package com.tutorialspoint;

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());
      }
   }
}

package com.tutorialspoint;

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

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