title: How can I parse dynamic content from a web page?
body: <p>I try to get a proxy list from this url:</p>
  
  <p><a href="http://spys.ru/en/free-proxy-list/" rel="nofollow">Free proxy list</a></p>
  
  <p>This would be cool, but port number is dynamic JavaScript content. How can I get JavaScript-generated content from this page? I have jsoup and djNativeSwing but I want do this in background thread. </p>
  
  <pre><code>JWebBrowser webBrowser = new JWebBrowser();
  webBrowser.navigate("http://spys.ru/en/free-proxy-list/");
  System.out.println(webBrowser.getHTMLContent());
  </code></pre>
  
  <p>this code returns a Null result. Help please.</p>
