How to access all the child elements of an HTML element in WinForms HTMLUIControl?

private void htmluiControl1_LoadFinished(object sender, System.EventArgs e)
{
     //Getting the body element in the HTML document
     IHTMLElement[] body = this.htmluiControl1.Document.GetElementsByName("body");
     //Collecting the children of the body element in a collection
     IHTMLElementsCollection elem = body[0].Children;
     foreach(IHTMLElement child in elem)
     {
         //searching for the children containing the OnClick attribute
         if(child.Attributes.Contains("ONCLICK") == true)
         {
             //Click event declaration for current children
             child.Click += new EventHandler(child_Click);
         }
     }
}
private void child_Click(object sender, EventArgs e)
{
     BubblingEventArgs bargs = HTMLUIControl.GetBublingEventArgs(e);
     //Accessing the element that is sending the event
     BaseElement elem = bargs.RootSender as BaseElement;
     //Validating the element for execution
     if( elem.ID == "img1" && elem is IMGElementImpl )
     {
         if(elem.Attributes["src"].Value == "sync.jpg")
             elem.Attributes["src"].Value = "syncfusion.gif";
         else
             elem.Attributes["src"].Value = "sync.jpg";
         this.htmluiControl1.ScrollToElement(elem);
     }
}
