help in extracting a tag out of a DOM of a web page
<p>I am creating a C# application in order to get the DOM info of a Web Page.
I cannot extract a TBODY tag using my application.
I am using</p>

<ul>
<li><p>the control WebBrowser shipped by Visual Studio</p></li>
<li><p>a reference to the Com Microsoft.mshtml 7.0.3300.0</p></li>
</ul>

<p>If I use the <a href="http://www.microsoft.com/downloads/details.aspx?familyid=e59c3964-672d-4511-bb3e-2d5e1db91038&amp;displaylang=en" rel="nofollow">Internet Explorer Developer Toolbar</a> ) I can see all information I need.</p>

<p>The  tag has id="tbody_id" and carries a list of  tags full of data
that are showed in attributes innertHTML and innertText.</p>

<p>Using the code below innertHtml and innertText are both null.
What I am doing wrong?
There are other controls that I can use</p>

<pre>
mshtml.IHTMLDocument3 domDoc = this.webBrowser.Document.DomDocument as mshtml.IHTMLDocument3;
mshtml.IHTMLElement element = domDoc.getElementById("tbody_id");
String innerHtml = element.innerHTML;
String innerText = element.innerText;
</pre>
