Hello,

I have manageg to create a validator, to validate an xml file with multiple 
schemas(17 xsd files). I have 4 xsd files that are simple. One other xsd file 
imports another xsd file directly from the file. for example, 

 <xsd:import namespace="http://www.xbrl.org/2003/instance" 
schemaLocation="http://www.xbrl.org/2003/xbrl-instance-2003-12-31.xsd"/>
  <xsd:import 
namespace="http://www.c-ebs.org/eu/fr/esrs/corep/2006-07-01/p-me-2006-07-01" 
schemaLocation="p-me-2006-07-01.xsd"/>

The "p-me" schema file imports another xsd file and so on. So i have like a 
tree of xsd files. The problem is, when i try to run my program without being 
on the internet, it runs perfectly. However, when i try to run it when being 
on the internet, it fails , saying duplicate declarations. 

In my program, (visual studio 2005 vb) , i am using a xmlschemaset in which 
i load all of the files that are declared in the xmlns:___... part of the 
instance. ie

sc.Add("http://www.xbrl.org/2003/instance", 
"C:\xbrl\COREPTaxonomy1.2\xbrl-instance-2003-12-31.xsd")

I then use the following code , before i start reading the xml. 

Dim settings As XmlReaderSettings = New XmlReaderSettings()
        settings.IgnoreWhitespace = True
        settings.IgnoreComments = True
        settings.Schemas = sc
        settings.ProhibitDtd = False
        settings.ValidationFlags = 
XmlSchemaValidationFlags.ReportValidationWarnings
        settings.ValidationFlags = 
XmlSchemaValidationFlags.ProcessSchemaLocation
        settings.ValidationFlags = XmlSchemaValidationFlags.AllowXmlAttributes
        settings.ValidationType = ValidationType.Schema 
'MKR_SA_EQU_instance.xml
        AddHandler settings.ValidationEventHandler, AddressOf 
SchemaValidationEventHandler

        Dim reader As XmlReader = 
XmlReader.Create("C:\xbrl\COREPTaxonomy1.2\MKR_SA_EQU_instance.xml", settings)

Dim manager As XmlNamespaceManager = New XmlNamespaceManager(reader.NameTable)
               manager.AddNamespace("d-mr", 
"http://www.c-ebs.org/eu/fr/esrs/corep/2006-07-01/d-mr-2006-07-01")
        manager.AddNamespace("d-ty", 
"http://www.c-ebs.org/eu/fr/esrs/corep/2006-07-01/d-mr-2006-07-01")
        manager.AddNamespace("iso4217", "http://www.xbrl.org/2003/iso4217")
               Dim validator As XmlSchemaValidator = New 
XmlSchemaValidator(reader.NameTable, sc, manager, settings.ValidationFlags)
      (SchemaValidationEventHandler)
        validator.Initialize()
        AddHandler validator.ValidationEventHandler, AddressOf 
SchemaValidationEventHandler

I then use , while reader.read
                  'do validations
                 end while

Can anybody help ?
Thank you
George
