Custom nav toolbar using sitemap roles

I have the following nav template:

<asp:Repeater ID="TopNavRepeat" runat="server"
DataSourceID="SiteMapDataSource1">
   <HeaderTemplate>
      <ul>
   </HeaderTemplate>
   <ItemTemplate>
      <li>
      <asp:HyperLink ID="HyperLink1" runat="server"
       Text='<%# Eval("Title") %>' NavigateUrl='<%# Eval("Url") %>'
       ToolTip='<%# Eval("Description") %>' />
      </li>
   </ItemTemplate>
   <FooterTemplate>
      </ul>
   </FooterTemplate>
</asp:Repeater>

How do I render the <li> for only those sitemap nodes for which the user's role has access? (i.e. roles="Admins" in Web.sitemap)

Thanks,
Mark

Methinks like:


<asp:Repeater ID="TopNavRepeat" runat="server"
DataSourceID="SiteMapDataSource1">
   <HeaderTemplate>
      <ul>
   </HeaderTemplate>
   <ItemTemplate>
    <% if(User.Identity.IsInRole( "Admins" ) { %>
      <li>
      <asp:HyperLink ID="HyperLink1" runat="server"
       Text='<%# Eval("Title") %>' NavigateUrl='<%# Eval("Url") %>'
       ToolTip='<%# Eval("Description") %>' />
      </li>
    <% } %>
   </ItemTemplate>
   <FooterTemplate>
      </ul>
   </FooterTemplate>
</asp:Repeater>

Right, but I have several roles and I want to drive it off the sitemap file like this:

<siteMapNode url="~/UserProfile.aspx" title="Profile" description="" roles="*" />

<siteMapNode url="~/Admin/Default.aspx" title="Admin" description="" roles="Admin" />

<siteMapNode url="~/Seller/Storefronts/Default.aspx" title="Storefronts" description="" roles="Seller"/>

Not sure how much conditional logic you can cram into a page without code-behind. I'm also not sure what I need to import to get "User.Identity.IsInRole" to resolve.
