MSXML VBA: Validating XML against XSD: “The '' namespace provided differs from the schema's targetNamespace.”

Question

I’m trying to validate an .XML file against an .XSD file with MSXML 6.0 DOM but on executing the code I’m getting this error message:

Test.xsd#/schema/target         


        

Answer 1

You shouldn't have to change anything in your xml/xsd, since together they are valid. The problem is in your code, so I would suggest to take a look at this sample that shows what I think is different than your code: when you add the XSD to the cache, use the target namespace http://somewhere.com/root instead of the empty string.

Answer 2

Try adding the namespace URI to the schema cache.

Sub XSD_Validation()
    Dim xmlDoc As MSXML2.DOMDocument60
    Dim objSchemaCache As New XMLSchemaCache60
    Dim objErr As MSXML2.IXMLDOMParseError

    objSchemaCache.Add "http://somewhere.com/root", LoadXmlFile("I:\Test.xsd")

    Set xmlDoc = LoadXmlFile("I:\Test.xml")
    Set xmlDoc.Schemas = objSchemaCache

    Set objErr = xmlDoc.Validate()
    If objErr.errorCode = 0 Then
        Debug.Print "No errors found"
    Else
        Debug.Print "Error parser: " & objErr.errorCode & "; " & objErr.reason
    End If
End Sub

Function LoadXmlFile(Path As String) As MSXML2.DOMDocument60
    Set LoadXmlFile = New MSXML2.DOMDocument60

    With LoadXmlFile
        .async = False
        .validateOnParse = False
        .resolveExternals = False
        .load Path
    End With
End Function
