If that is a valid representation then why would this not work:

Public Class ViewPagePage
>    Public Function GetPage() As Boolean
>        ' Just instantiate the version of Parser that suits your requirements? e.g:
>        Dim loParser As DerivedParser = New DerivedParser()
>        'Etc
>        Return loParser.ParseForTable()
>    End Function
>End Class

But, where in the client class would be the code for the ReplaceWithThisContent() method?
