displaying hierarchical xml in asp.net - vb

I've tried converting some code from c# to vb but it's not working and I'm not sure why. It's supposed to render hierarchical xml.

Here's the code...

Private Sub Page_Load(sender As Object, e As EventArgs)
    Dim doc As New XmlDocument()
    doc.Load(Server.MapPath("~/myxml/getbooking.xml"))

    _rep1.DataSource = doc.FirstChild
    _rep1.DataBind()
End Sub

and

<asp:Repeater id="_rep1" runat="server" EnableViewState="false">
 <itemTemplate>
   Publisher: <%# CType(Container.DataItem, XmlNode).Attributes("name").Value  %><br/>
   <asp:Repeater runat="server" EnableViewState="false" DataSource='<%# Container.DataItem %>' >
     <itemTemplate>
       Author: <%# CType(Container.DataItem, XmlNode).Attributes("name").Value %><br/>
       <asp:Repeater runat="server" EnableViewState="false"
                  DataSource='<%# Container.DataItem %>' >
          &l开发者_如何学Ct;itemTemplate>
             <i>
          <%# CType(Container.DataItem, XmlNode).Attributes("name").Value  %>
          </i><br />
          </itemTemplate>
        </asp:Repeater>
     </itemTemplate>
   </asp:Repeater>
   <hr />
 </itemTemplate>
</asp:Repeater>

with the xml...

Any ideas?

Why not output it with the <xmp> tag around the xml?

<xmp>    
   <asp:literal id="myxml" runat="server" />
</xmp>

and in the codebehind

myxml.Text = doc.InnerXml;
