xml .net newbie

[janetb]

Had a repeater giving out an rss xml data feed, but it took too long to load, so I'm using an ajax incremental page loader and need to get the xml into an innerhtml format so I can write it back to the page's div tag via a web service. I've tried researching for days, but I'm having trouble getting the description piece (the title and link come through fine) and wondered if anyone would be willing to explain it and help out?

<asp:Repeater ID="rptr" runat="server" DataSourceID="XmlDataSource">
                <ItemTemplate>
                <<%# XPath("title") %><br />
                <%# XPath("description") %><a href='<%# XPath("link") %>'>...details</a><br /><br />
                </ItemTemplate>
                </asp:Repeater>
                </fieldset>
                <asp:XmlDataSource ID="XmlDataSource" runat="server" DataFile="http://www.exploreasheville.com/rss-feeds/asheville-happenings/index.aspx" XPath="rss/channel/item" >
                </asp:XmlDataSource>

The following works with only (0) and (1), until I try to pull back the description (I'm guessing (2) because of xml page structure below), then I only get [object Object] .

Try
    	Dim myStr As String 
                Dim m_xmld As System.Xml.XmlDocument
                Dim m_nodelist As System.Xml.XmlNodeList
                Dim m_node As System.Xml.XmlNode
                m_xmld = New System.Xml.XmlDocument()
                m_xmld.Load("http://www.exploreasheville.com/rss-feeds/asheville-happenings/index.aspx")
                m_nodelist = m_xmld.SelectNodes("rss/channel/item")
                'Loop through the nodes
                For Each m_node In m_nodelist
                    'Get the Element Values
                    Dim titleValue = m_node.ChildNodes.Item(0).InnerText
                    Dim linkValue = m_node.ChildNodes.Item(1).InnerText
                    myStr &= titleValue & "<br />" & "description to follow&nbsp;<a href='" & _
                            linkValue & "'>...details</a><br />"
                Next
            Catch errorVariable As Exception
                'Error trapping
                myStr &= errorVariable.ToString()
            End Try
            Return myStr

When I view the source of the page, this is the structure:

<?xml version="1.0" encoding="UTF-8"?>
    <rss version="2.0" xmlns:rei="http://r-effects.com">
      <channel>
        <title>Asheville Happenings</title>

Found the answer - had to add this to the webconfig. Hope it helps someone else.
