How to break out the class in DOM using autoit?

Using the DOM stuff and need to pull out the innerTEXT of the class="sr tum"
Here is what I am using so far with negative results..  I don't see a command for _IEGetObjByClass but that is what it looks like I need.  Can anyone push me in the right direction to get back on track...

Local $oDiv = _IEGetObjByName($oIE, "sr tum")
Local $oJob = _IEPropertyGet($oDiv, "innertext")
ConsoleWrite($oJob & @CRLF) ; Ans should be: [url="http://www.vahud.com"]www.vahud.com[/url]

<a id="rss1" onmouseup="return href="[url="http://www.vahud.com/"]http://www.vahud.com/[/url]">
</h3>
<div class="rss1" aria-label="Result today" role="button" tabindex="0">
<div>
<div class="sr tum">
<cite>www.vahud.com/</cite>
</div>
