I have created a XmlDocument that contains the exact layout that
siteMap uses, and then I bind my Menu object to it:

       Dim xml As XmlDocument
       xml = DirectCast(Session("MenuData"), XmlDocument)

       Dim xmlDS As New XmlDataSource()
       xmlDS.Data = xml.OuterXml

       MainMenu.DataSource = xmlDS
       Dim mb As New MenuItemBinding()
       mb.DataMember = "SiteMapNode"
       mb.TextField = "Title"
       mb.NavigateUrlField = "url"

       MainMenu.DataBindings.Add(mb)
       MainMenu.DataBind()

The problem is when it displays it always shows the root element
("siteMap").  If you use a static site map you have an option to turn
this off; am I missing the ability to do that since I'm using XML?

Thanks,
