Thanks to the answer I received here I was able to produce the xml file.
http://www.experts-exchange.com/Microsoft/Development/MS-SQL-Server/SQL-Server-2005/Q_28015259.html

How do I control whether the top line says
<?xml version="1.0"?>  or <?xml version='1.0'?>  single or double quotes

How do I produce an xsd for the xml files I produce?

I'm writing a c# executable in visual studio 2008 .net framework 3.5.

I tried adding it just after I call the parsexml routine and get the message doc does not exist in the current context.

Not sure if it's relevant, but the xsd needs to be in a separate file.
