How to catch onpropertychange event for DIV HTML element in C# BHO

Hi.

I've created a generic DOM event handler in my C# BHO code as follows:

-----
public delegate void DHTMLEvent(IHTMLEventObj e);

/// Generic Event handler for HTML DOM objects.
/// Handles a basic event object which receives an IHTMLEventObj which
/// applies to all document events raised.

[ComVisible(true)]
public class DHTMLEventHandler
{
   public DHTMLEvent Handler;
   HTMLDocument Document;

   public DHTMLEventHandler(mshtml.HTMLDocument doc)
   {
      this.Document = doc;
   }

    [DispId(0)]
    public void Call()
    {
       Handler(Document.parentWindow.@event);
     }
}
----

I've used the code above to sucessfully create an event handler for the onclick event of the document element of the current webbrowser.

I now want to create an event handler to capture when the innerHTML property of a DIV tag contained in the document changes. I've done the following:

--------
IHTMLDocument3 doc2 = (IHTMLDocument3)((IWebBrowser2)pDisp).Document;
DHTMLEventHandler Handler2 = new DHTMLEventHandler(doc2 as mshtml.HTMLDocument);
Handler2.Handler += new DHTMLEvent(OnDocumentPropertyChanged);
doc2.onpropertychange = Handler2;
--------

I've then coded the event handler as follows:

---------
public void OnDocumentPropertyChanged(IHTMLEventObj evo)
{
    IHTMLElement2 element = (IHTMLElement2)evo.srcElement;
           
     if (evo != null)
     {
        MessageBox.Show(evo.srcElement.innerHTML);
      }
}
---------
This code seems to capture when a property changes, but it doesn't correctly reflect the source element that raised the event.

Can anyone help me with identifying the source element that raised the onpropertychanged event or suggest another way of capturing the change of a child DIV tags inner HTML property.
