jsoup - Set HTML
Following example will showcase use of method to set, prepend or append html to a dom element after parsing an HTML String into a Document object.
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.
Description
Element object represent a dom elment and provides various method to set, prepend or append html to a dom element.
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;
public class JsoupTester {
public static void main(String[] args) {
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());
div.prepend("<p>Initial Text</p>");
System.out.println("After Prepend :\n" + div.outerHtml());
div.append("<p>End Text</p>");
System.out.println("After Append :\n" + div.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.
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> After Prepend : <div id="sampleDiv"> <p>Initial Text</p> <p>This is a sample content.</p> </div> After Append : <div id="sampleDiv"> <p>Initial Text</p> <p>This is a sample content.</p> <p>End Text</p> </div> Outer HTML Before Modification : <span>Sample Content</span> Outer HTML After Modification : <span>Sample Content</span>
