Hi Radu,Thank you very much, I was able to work out all of the issues I was having based on your feedback. I was indeed working with document types, which require special handling as you described.Regards,Vance> -------- Original Message --------> Subject: RE: How can I iterate through children (elements and> attributes) of a SchemaType?> From: Radu Preotiuc-Pietro <[EMAIL PROTECTED]>> Date: Tue, April 03, 2007 8:54 pm> To: [email protected]> > You are going to have to explain to me what you mean by "element types"> exactly.> > I think you may be confused by our use of "document type".
