xml deserialization error in namespace or root directory

[mehrlicht]

I have a xml file that was not generated by me and I cannot change it because a similar file is generated each day and I must read it as it is.

it begins thus:

<?xml version="1.0" encoding="UTF-8" ?>
    <Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2"
    xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
    xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2"
     xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"
    xmlns:mcd="urn:acss:ccf:facturacaoelectronica:schema:xsd:Normalizados">
    <ext:UBLExtensions>
    <ext:UBLExtension>
    <ext:ExtensionVersionID>ACSS:CCF:NormalizadosExtension:1.0</ext:ExtensionVersionID>
    <ext:ExtensionContent>
    <mcd:NormalizadosExtension>
    ....

The class generated through xsd.exe from a partial Normalizados.xsd schema begins like this:

 Option Strict Off
Option Explicit On

Imports System.Xml.Serialization

'
'This source code was auto-generated by xsd, Version=4.6.81.0.
'

'''<remarks/>
<System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.6.81.0"),  _
 System.SerializableAttribute(),  _
 System.Diagnostics.DebuggerStepThroughAttribute(),  _
 System.ComponentModel.DesignerCategoryAttribute("code"),  _
 System.Xml.Serialization.XmlTypeAttribute([Namespace]:="urn:acss:ccf:facturacaoelectronica:schema:xsd:Normalizados"),  _
 System.Xml.Serialization.XmlRootAttribute("NormalizadosExtension", [Namespace]:="urn:acss:ccf:facturacaoelectronica:schema:xsd:Normalizados", IsNullable:=false)>  _
Partial Public Class NormalizadosExtensionType

the code to deserialize is this:

Public Sub lerxml()

            Dim ObjStreamReader As New StreamReader(ficheiroxml, System.Text.Encoding.Default)
            Dim norm As New NormalizadosExtensionType()
            Dim dmcd As New XmlSerializer(norm.GetType)
            norm = dmcd.Deserialize(ObjStreamReader)
    ...

End Sub

the last line throws an error: An unhandled exception of type 'System.InvalidOperationException' occurred in System.Xml.dll Additional information: There is an error in XML document (5, 2).

this means an error on the xml file when Invoice first appears.

inner exception shows "<Invoice xmlns='urn: oasis:names:specification:ubl:schema:xsd:Invoice-*​2'> was not expected."

The class I want to be the root (because I only have the schema for its subclass and don't really need anything outside it), Normalizados, is a subclass of a subclass of a subclass of Invoice ( Invoice > UBLExtension > ExtensionContent > NormalizadosExtension )

What's wrong with the code? Thanks

Checking through MSDN docs, you need to restore the object's state when performing deserialization.

norm = CType(dcmd.Deserialize(reader), NormalizadosExtensionType)

MSDN XmlSerializer.Deserialize()

Same error persists.
