GeckoFX - Get GetHtmlElementById

Question

I've Been struggling with this for over 5 hours now

Example:

 <div id='xx'>content</div> 

How can i access Content of that div via GetHtmlElementById or any other solution based on "Id"

i tried

GeckoElement el = browser.Document.GetElementById("xx");
MessageBox.Show(el.TextContent); 

and im getting NullRefferenceException (Object reference not set to an instance of an object.)

Other example :Navigating to google.co.uk

browser.DocumentCompleted += delegate { 
                MessageBox.Show(browser.DomDocument.GetElementById("gbqfsa").TextContent);

            };

MessageBox should show me "Google Search" but no luck

System.NullReferenceException was unhandled by user code
Message=Object reference not set to an instance of an object.

Answer 1

            GeckoHtmlElement ele;
            ele = geckoWebBrowser1.Document.GetHtmlElementById("myData");
            MessageBox.Show(ele.GetAttribute("Value"));

This works for me.
