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 id='googleA' href='www.google.com'>Google</a></div>"
         + "<div class='comments'><a href='www.sample1.com'>Sample1</a>"
         + "<a href='www.sample2.com'>Sample2</a>"
         + "<a href='www.sample3.com'>Sample3</a><div>"
         + "<div id='imageDiv' class='header'><img name='google' src='google.png' />"
         + "<img name='yahoo' src='yahoo.jpg' />"
      Document document = Jsoup.parse(html);

      //Example: set attribute
      Element link = document.getElementById("googleA");
      System.out.println("Outer HTML Before Modification :"  + link.outerHtml());
      System.out.println("Outer HTML After Modification :"  + link.outerHtml());
      //Example: add class
      Element div = document.getElementById("sampleDiv");
      System.out.println("Outer HTML Before Modification :"  + div.outerHtml());
      System.out.println("Outer HTML After Modification :"  + div.outerHtml());
      //Example: remove class
      Element div1 = document.getElementById("imageDiv");
      System.out.println("Outer HTML Before Modification :"  + div1.outerHtml());
      System.out.println("Outer HTML After Modification :"  + div1.outerHtml());
      //Example: bulk update
      Elements links = document.select("div.comments a");
      System.out.println("Outer HTML Before Modification :"  + links.outerHtml());
      links.attr("rel", "nofollow");
      System.out.println("Outer HTML Before Modification :"  + links.outerHtml());

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.
