View Sharepoint content with ASP.net

I create a webpage to view SharePoint content. I am able to get Title from SharePoint Lists.asm service. But I cannot get the body text/images for each titles. The following is my code:



   Private Function GetListNode() As XmlNode

        Dim RCPILists As New engage.Lists()
        RCPILists.Credentials = New System.Net.NetworkCredential("TestUser1", "Pwd1", "Domain1")
        Dim TEXT1 As XmlNode = RCPILists.GetListItems("{A3621D46-5961-4B61-BC70-E2BFE7A31BC4}", Nothing, Nothing, Nothing, Nothing, Nothing, Nothing)
        Return TEXT1

    End Function
   

    Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim node As XmlNode = GetListNode()
        Dim xr As New XmlTextReader(node.OuterXml, XmlNodeType.Element, Nothing)
        Dim ds As New DataSet
        ds.ReadXml(xr)
        SharePointListBox.DataSource = ds.Tables("row")
        SharePointListBox.DataTextField = "ows_LinkTitle"
        SharePointListBox.DataBind()

    End Sub
