XPath issue - C# / C Sharp

dba123

I have an issue where I want to put an image right before the text for each
record below in a GridView. The problem is, the XPath is rss/channel/item".
So since I have the picture in my XML file under rss/channel/image/podcast
then how can I tell it to use rss/channel/image/podcast for the picture but
still use just rss/channel/item for the rest?

I've tried to change the XPath in the XMLDataSource to "rss/channel" then
set the paths in the Columns to item/description, item/title, and
/image/podcast but the GridView stops at the first record if I do this.

<asp:GridView
ID="GridView_Podcasts"
runat="server"
AllowPaging="true"
PageSize="5"
AllowSorting="true"
AutoGenerateColumns = "False"
DataSourceID="PodcastsXML"
BackColor="#FFFCC5"
BorderColor="Tan"
BorderWidth="1px"
CellPadding="2"
ForeColor="#FFFFFF"
GridLines="None">
<Columns>
<asp:TemplateField HeaderText="Title">
<ItemTemplate>
<asp:Image ID="Image1"
ImageUrl='<%#XPath("image/podcast")%>' runat="server" />
<asp:HyperLink ID="HyperLink1" runat="server"
Target="_blank" NavigateUrl='<%#XPath("title") %>' >
<%#XPath("title")%></asp:HyperLink>
 
<asp:Label ID="Label1" runat="server"
Text=<%#XPath("description")%>></asp:Label>
 
</ItemTemplate>
</asp:TemplateField>
</Columns>

<FooterStyle BackColor="#000000" />
<SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite" />
<PagerStyle BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue"
HorizontalAlign="Center" />
<HeaderStyle BackColor="#EFBA67" Font-Bold="True" />
<AlternatingRowStyle BackColor="#F8F8F7" />

</asp:GridView>
<asp:XmlDataSource ID="PodcastsXML" runat="server"
DataFile="~/interact/podcasts/rss/podcast.xml"
XPath="rss/channel/item"></asp:XmlDataSource>

Here's my XML:

The xml document has a default namespace. You will have to enable
somehow the namespace resolution in the grid (dunno if it's feasible)
or change the xpath to something like //[name()='rss']

Check for a previous post about Enterprise Block configuration files.

I resolved it:

<asp:Image ID="Image1"
ImageUrl='<%#XPath("../image/podcast")%>' runat="server" />
