System.Web.UI.Control.Controls Collection

As part of an abstracted method for changing styles on <a> HtmlAnchors I tried to recurse down through child controls starting with a parameter control. However, the <a> HtmlAnchors within the <td> HtmlTableCells are never seen by the method. aspx and asp.cs extract as follows:

------------------

Code:

<tr id="trSupplierLinks" runat="server">
    <td valign="top"><a class="navagation_link_normal" href='<%=Application["VirPath"]%>supplier/details_new.aspx'>Details 
            &amp; Service Zones</a></td>
    <td valign="top">|</td>
    <td valign="top"><a class="navagation_link_normal" href='<%=Application["VirPath"]%>supplier/instructions.aspx'>Instructions 
            &amp;<br>
            Information</a></td>
    <td valign="top">|</td>
    <td valign="top"><a class="navagation_link_normal" href='<%=Application["VirPath"]%>supplier/rates_manage.aspx'>General 
            Waste Schedule</a></td>
    <td valign="top">|</td>
    <td valign="top"><a class="navagation_link_normal" href='<%=Application["VirPath"]%>supplier/rates_manage_clean.aspx'>Clean 
            Fill Schedule</a></td>
    <td valign="top">|</td>
    <td valign="top"><a class="navagation_link_normal" href='<%=Application["VirPath"]%>supplier/rates_manage_green.aspx'>Green 
            Waste Schedule</a></td>
    <td valign="top">|</td>
    <td valign="top"><a class="navagation_link_normal" href='<%=Application["VirPath"]%>supplier/rates_manage.aspx?logout=true'>Log 
            Out</a></td>
    <td>
    <asp:Literal ID="litTest" Visible="False" Runat=server>
            <td valign="top">|</td>
    <td valign="top"><a class="navagation_link_normal" href='order_receipting.aspx'>Order 
            Receipting</a></td></asp:Literal></td>
</tr>

Code:

protected void UpdateNavagationLinks(Control objLinksParent)

        {
            HtmlAnchor objNavLink;
            string sCurrentURL = Request.ServerVariables["URL"];
            string sStyleClass;
            foreach (Control objNavControl in objLinksParent.Controls)
            {
                if(objNavControl.GetType() == Type.GetType("HtmlAnchor"))
                {
                    objNavLink = (HtmlAnchor)objNavControl;
                    sStyleClass = objNavLink.Attributes["class"];
                    if(sStyleClass.IndexOf("navagation_link") < 1)
                    {
                        continue;
                    }
                    aText.Text = aText.Text + objNavLink.HRef + " " + sCurrentURL;
                    if(objNavLink.HRef == sCurrentURL)
                    {
                        sStyleClass = "navagation_link_current";
                    }
                    else
                    {
                        sStyleClass = "navagation_link_normal";
                    }
                }
                UpdateNavagationLinks(objNavControl);
            }

        }

Strangly enough the "|"'s *do* show up in the method (as HtmlLiterals). But the anchor tags dont.

Thanks in advance.
