Show data of MemoryStream in a literal control

I am using the XMLtextwriter to create  XML data. The writer writes the data into a memorystream. Once it is finished I would like to show the XML data in a literal control, before I use an XSL file for a transformation.

My code:

        Dim oMemoryStream As New System.IO.MemoryStream
        Dim oXMLWriter As System.Xml.XmlTextWriter
        oXMLWriter = New System.Xml.XmlTextWriter(oMemoryStream, System.Text.Encoding.UTF8)

        With oXMLWriter
            .Formatting = System.Xml.Formatting.Indented
            .Indentation = 4
            .IndentChar = CChar(" ")
            .WriteStartDocument()
            .WriteStartElement("navigation")

            Call WriteNavigationItems(oXMLWriter, PageInfo.AtaChapterID)

            .WriteEndElement()
            .WriteEndDocument()
        End With

        oXMLWriter.Flush()

        oMemoryStream.Position = 0
        Dim XMLdoc As New XPathDocument(oMemoryStream)
        oMemoryStream.Close()

        Dim stylesheet As New XslTransform
        stylesheet.Load("E:\BA - Projects\Bright Alley\wwwroot\FE\ba_controls\default\navigation.xslt")

        Dim oStringWriter As New System.IO.StringWriter
        stylesheet.Transform(XMLdoc.CreateNavigator(), Nothing, oStringWriter, Nothing)
        ltlNavigation.Text = oStringWriter.ToString

        oXMLWriter.Close()
