Lettura XML UTF8 FAT.El.

Ciao a tutti,
a seguito del post di prima sulla visualizzazione della fattura che ho poi risolto,
ora sono in preda alla pratica del leggere il contenuto.

ho effettuato una buona parte del lavoro appoggiandomi ad una classe creata da me.

Per poi andare a ricreare qui nel button gli elementi.

        If pathexplorer = "" Then
            MsgBox("Select a Valid Invoice Before Start")
            Exit Sub
        End If
        MsgBox(pathexplorer)
            Dim PercorsoFile As String = pathexplorer
            Dim fatturaElettronica As Fattura.FatturaElettronica = New Fattura.FatturaElettronica()
            Dim serializzare As XmlSerializer = New XmlSerializer(GetType(Fattura.FatturaElettronica))
            Dim readerLettura As StreamReader = New StreamReader(PercorsoFile)
            fatturaElettronica = CType(serializzare.Deserialize(readerLettura), Fattura.FatturaElettronica)
            readerLettura.Close()
            Dim NomeFornitore As String = fatturaElettronica.FatturaElettronicaHeader.CedentePrestatore.DatiAnagrafici.Anagrafica.Denominazione
            Dim totaleImporto As Decimal = fatturaElettronica.FatturaElettronicaBody.DatiGenerali.DatiGeneraliDocumento.ImportoTotaleDocumento
            Dim numfattura As Integer = fatturaElettronica.FatturaElettronicaHeader.DatiTrasmissione.ProgressivoInvio
            Dim piva As String = fatturaElettronica.FatturaElettronicaHeader.CedentePrestatore.DatiAnagrafici.IdFiscaleIVA.IdCodice

            MsgBox("Fornitore : " & NomeFornitore & " totaleImporto " & totaleImporto & " num fatt " & numfattura & "p iva" & piva)
        ' Catch ex As Exception
        ' MessageBox.Show(ex.Message)
        '  End Try
    End Sub

ma continua sempre e comunque a darmi errore
System.InvalidOperationException: 'There is an error in XML document (1, 56).'
InvalidOperationException: <FatturaElettronica xmlns='http://ivaservizi.agenziaentrate.gov.it/docs/xsd/fatture/v1.2'> was not expected.

il char 56, corrispnonde a ns3:fatturaelettronica
<?xml version="1.0" encoding="UTF-8"?><ns3:FatturaElettronica xmlns:ns3="http://ivaservizi.agenziaentrate.gov.it/docs/xsd/fatture/v1.2" xmlns:ns2="http://www.w3.org/2000/09/xmldsi#" versione="FPR12">

idee, suggerimenti??
è due giorni che ci piango sopra..
