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

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

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

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 Append :
