public class JsoupTester {
public static void main(String[] args) {
  </span><span class="typ">String</span><span class="pln"> html </span><span class="pun">=</span><span class="pln"> </span><span class="str">"&lt;html&gt;&lt;head&gt;&lt;title&gt;Sample Title&lt;/title&gt;&lt;/head&gt;"</span><span class="pln">
