Repeater and XmlDataSource

[Jon Davis]

My repeater is not repeating any items.

I am trying to use an XmlDataSource to load a custom .sitemap file having
content similar to as follows:

<siteMap>
<siteMapNode title="Home" description="Ho me" url="~/default.aspx">
<siteMapNode title="Buy" description="Bu y stuff"
url="~/Buy.aspx" />
<siteMapNode title="Sell" description="Se ll stuff"
url="~/sell.aspx" />
</siteMapNode>
</siteMap>

I've put this file, called "Nav.sitema p", into the path
"~/App_Files/navXML/Nav.config".

In my TopNav.ascx file, I have a repeater as such:
<div>
<ul><asp:Repeat er ID="Repeater1" runat="server">
<ItemTemplate>< li><a href='<%# XPath("@url") %>'><%# XPath("@title")
%></a></li></ItemTemplate>
</asp:Repeater>
</ul>
</div>

In the code-behind, I have something similar to the following:

protected void Page_Load(objec t sender, EventArgs e)
{
XmlDataSource xmlSource = new XmlDataSource() ;
xmlSource.DataF ile = MapPath("~/App_Files/navXML/Nav.sitemap");
xmlSource.XPath = "/siteMap/siteMapNode/siteMapNode";
xmlSource.DataB ind();
Repeater1.DataS ource = xmlSource;
Repeater1.DataB ind();
}

When I run this as posted on the machine I'm posting this newsgroup post (at
home), it works fine, but for some reason on the actual development server
at the office the output is blank. If I add a <HeaderTempla te />, the
repeater shows itself to be functional, but simply no items are displayed.
There is no error messages, the <ItemTemplate /simply never renders any
items. I've validated that the XPath string is identical to what's described
above. What could be some of the causes of this behavior? Any ideas??

Thanks,
Jon
