下面的示例获取html页面中a元素的相对和绝对URL的方法。
String url="http://www.learnfk.com/"; Document document=Jsoup.connect(url).get(); Element link=document.select("a").first();System.out.println("Relative Link: " + link.attr("href")); System.out.println("Absolute Link: " + link.attr("abs:href")); System.out.println("Absolute Link: " + link.absUrl("href"));
元素对象代表dom元素，并提供获取html页面中相对和绝对URL的方法。
Element.absUrl示例

C:\jsoup>javac JsoupTester.java
现在运行JsoupTester以查看输出。
C:\jsoup>java JsoupTester
查看输出。
