displaying hierarchical xml in asp.net - vb -

-

i've tried converting code c# vb it's not working , i'm not sure why. it's supposed render hierarchical xml.

here's code...

private sub page_load(sender object, e eventargs)     dim doc 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 %>' >           <itemtemplate>              <i>           <%# ctype(container.dataitem, xmlnode).attributes("name").value  %>           </i><br />           </itemtemplate>         </asp:repeater>      </itemtemplate>    </asp:repeater>    <hr />  </itemtemplate> </asp:repeater>

with xml...

<publishers>  <publisher name="new moon books" city="boston"             state="ma" country="usa">    <author name="albert ringer   ">      <title name="is anger enemy?" />      <title name="life without fear" />    </author>    <author name="john white   ">      <title name="prolonged data deprivation " />    </author>    <author name="charlene locksley   ">      <title name="emotional security: new algorithm" />    </author>    <author name="marjorie green   ">      <title name="you can combat computer stress!" />    </author>  </publisher>  <publisher name="binnet , hardley" city="washington"              state="dc" country="usa">    <author name="sylvia panteley   ">      <title name="onions, leeks, , garlic" />    </author>    <author name="burt gringlesby   ">      <title name="sushi, anyone?" />    </author>    <author name="innes del castillo   ">      <title name="silicon valley gastronomic treats" />    </author>    <author name="michel defrance   ">      <title name="the gourmet microwave" />    </author>    <author name="livia karsen   ">      <title name="computer phobic , non-phobic" />    </author>  </publisher>  <!-- ... --> </publishers>

any ideas?

why not output <xmp> tag around xml?

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

and in codebehind

myxml.text = doc.innerxml;
