I can't seem to find out how to run an XML object through an XSLT to get a new XML object. I've tried the following code:

  Private Function TransformDocument(ByVal doc As XmlDocument) As XmlDocument
    Try
      Dim xslt As New XslTransform
      xslt.Load("D:\Convert.xslt")
      Dim reader As XmlReader
      reader = xslt.Transform(doc, Nothing)
      TransformDocument.Load(reader)
    Catch ex As Exception
      MessageBox.Show("TransformDocument" & vbCr & ex.Message & vbCr & ex.GetType.ToString)
    End Try
  End Function

But I get the following error message:

TransformDocument
file:///D:/Convert.xslt(2,2) :
System.XML.XSL.XSTLCompileException

Can anyone give me a hint as to how to do this? If my code model is all wrong, I'm happy to change it in any way, I'm not married to the structure. I just want to do all this internally, without writing XML files out to the hard drive.

Thanks

OK, I found out there were some errors in my XSLT document (not coding errors, but additional info that I copied out of the XSD that shouldn't have been there).

So, the code runs without erroring, BUT it doesn't do anything! I get the same XML document back as the one I give it. Can anyone out there tell me how to apply an XSL template to an XML document? I can't believe how hard this is! You would think it would be one of the simplest things in the .NET world, but I can't find ANYONE who can give me code that works! Even when I write the XML out to a file (which I HATE to do, I've already got it in memory, why should I have to write it out to a file and then re-read it???)

Isn't there ANYONE out there who has applied an XSLT to an XML document in memory???????
