Following example will showcase use of selector methods after parsing an HTML String into a Document object. jsoup supports selectors similar to CSS Selectors.
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”.
Description
The document.select(expression) method parses the given CSS selector expression to select a html 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; 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>" + "<h3><a>Sample</a><h3>" +"</div>" + "<div id=''imageDiv'' class=''header''><img name=''google'' src=''google.png'' />" + "<img name=''yahoo'' src=''yahoo.jpg'' />" +"</div>" +"</body></html>"; Document document = Jsoup.parse(html); //a with href Elements links = document.select("a[href]"); for (Element link : links) { System.out.println("Href: " + link.attr("href")); System.out.println("Text: " + link.text()); } // img with src ending .png Elements pngs = document.select("img[src$=.png]"); for (Element png : pngs) { System.out.println("Name: " + png.attr("name")); } // div with class=header Element headerDiv = document.select("div.header").first(); System.out.println("Id: " + headerDiv.id()); // direct a after h3 Elements sampleLinks = document.select("h3 > a"); for (Element link : sampleLinks) { System.out.println("Text: " + link.text()); } } }
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.
