Validate WebDAV

Question

Hi,

Found this:

    Private DAVErrors As String = Nothing
    Public Function DAVDetector(ByVal InputXML As String) As String
        Dim MyXML As New XmlDocument
        MyXML.LoadXml(File.ReadAllText(InputXML))
        Dim MySchema As XmlReader = XmlReader.Create(New StringReader(My.Resources.AppResources.webdav))
        MyXML.Schemas.Add("", MySchema)
        MyXML.Validate(AddressOf ValidationEventHandler)
        DAVDetector = DAVErrors
    End Function
    Sub ValidationEventHandler(ByVal sender As Object, ByVal e As Schema.ValidationEventArgs)
        DAVErrors += e.Message + vbCrLf + vbCrLf
    End Sub

And I get error:

The targetNamespace parameter '' should be the same value as the targetNamespace 'DAV:' of the schema.

Answer 1

To solve the first problem, try specifying the name according to the error message:

 MyXML.Schemas.Add("DAV:", MySchema) ' instead of  MyXML.Schemas.Add("", MySchema)

However the input file does not seem to correspond to the schema. For example, the <contentclass> element is not defined. Maybe you should use a different schema.
