Syntax

Document document = Jsoup.parse(html);
Element div = document.getElementById("sampleDiv");     
div.html("<p>This is a sample content.</p>");   
div.prepend("<p>Initial Text</p>");
div.append("<p>End Text</p>");

Where

  • document − document object represents the HTML DOM.

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

  • html − HTML String.

  • div − Element object represent the html node element representing anchor tag.

  • div.html() − html(content) method replaces the element's outer html with the corresponding value.

  • div.prepend() − prepend(content) method adds the content before the outer html.

  • div.append() − append(content) method adds the content after the outer html.

Example - Change HTML Content

JsoupTester.java

package com.tutorialspoint;

import java.io.IOException;

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

public class JsoupTester {
   public static void main(String[] args) throws IOException {
   
      String html = "<html><head><title>Sample Title</title></head>"
         + "<body>"
         + "<div id='sampleDiv'><a id='googleA' href='www.google.com'>Google</a></div>"
         +"</body></html>";
      Document document = Jsoup.parse(html);

      Element div = document.getElementById("sampleDiv");
      System.out.println("Outer HTML Before Modification :\n"  + div.outerHtml());
      div.html("<p>This is a sample content.</p>");
      System.out.println("Outer HTML After Modification :\n"  + div.outerHtml());
   }
}

Verify the result

Compile and run the JsoupTester to verify the result −

Outer HTML Before Modification :
<div id="sampleDiv">
 <a id="googleA" href="www.google.com">Google</a>
</div>
Outer HTML After Modification :
<div id="sampleDiv">
 <p>This is a sample content.</p>
</div>

Example - Prepending HTML

JsoupTester.java

package com.tutorialspoint;

import java.io.IOException;

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

public class JsoupTester {
   public static void main(String[] args) throws IOException {
   
      String html = "<html><head><title>Sample Title</title></head>"
         + "<body>"
         + "<div id='sampleDiv'><a id='googleA' href='www.google.com'>Google</a></div>"
         +"</body></html>";
      Document document = Jsoup.parse(html);
      Element div = document.getElementById("sampleDiv");
      System.out.println("Outer HTML Before Modification :\n"  + div.outerHtml());
      div.prepend("<p>Initial Text</p>");
      System.out.println("After Prepend :\n"  + div.outerHtml());
   }
}

Verify the result

Compile and run the JsoupTester to verify the result −

Outer HTML Before Modification :
<div id="sampleDiv">
 <a id="googleA" href="www.google.com">Google</a>
</div>
After Prepend :
<div id="sampleDiv">
 <p>Initial Text</p>
 <a id="googleA" href="www.google.com">Google</a>
</div>

Example - Appending HTML

JsoupTester.java

package com.tutorialspoint;

import java.io.IOException;

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

public class JsoupTester {
   public static void main(String[] args) throws IOException {
   
      String html = "<html><head><title>Sample Title</title></head>"
         + "<body>"
         + "<div id='sampleDiv'><a id='googleA' href='www.google.com'>Google</a></div>"
         +"</body></html>";
      Document document = Jsoup.parse(html);
      Element div = document.getElementById("sampleDiv");
      System.out.println("Outer HTML Before Modification :\n"  + div.outerHtml());
      
      div.append("<p>End Text</p>");
      System.out.println("After Append :\n"  + div.outerHtml());  
   }
}

Verify the result
