title: Parsing of a dynamic web page using HtmlUnit in java is not working
body: <p><a href="https://i.stack.imgur.com/FdsDc.jpg" rel="nofollow noreferrer">Image explaining the data to be extracted</a></p>
  
  <p>I'm trying to extract data from a <a href="https://earth.nullschool.net/#current/wind/isobaric/500hPa/orthographic=-283.71,14.19,2183/loc=76.850,11.440" rel="nofollow noreferrer">web page</a> (marked red in the image) using  <a href="http://htmlunit.sourceforge.net/" rel="nofollow noreferrer">HtmlUnit</a> library of java. But I can't get that particular value.</p>
  
  <pre><code>WebClient webClient = new WebClient(BrowserVersion.CHROME);
  Thread.sleep(5000);
  HtmlPage page = webClient.getPage("https://earth.nullschool.net/#current/wind/isobaric/500hPa/orthographic=-283.71,14.19,2183/loc=76.850,11.440");
  Thread.sleep(5000);
  System.out.println(page.asXml());
  </code></pre>
  
  <p>I checked the html which I got on console window. It doesn't contain the value.    </p>
  
  <pre><code>&lt;p&gt;
    &lt;span id="location-wind" class="location"&gt;
            &lt;/span&gt;
    &lt;span id="location-wind-units" class="location text-button"&gt;
            &lt;/span&gt;
  &lt;/p&gt;
  </code></pre>
