Generating XML from Excel2002 using XSD

[Ben]

Hi
I understand that XL2003 offers nice XML features that could do what I
want easily.
But I am not sure about what XL2002 Pro can let me do.

I need to generate pretty basic XML in Excel 2002 VBA.

I have an idea of my XSD schema -
say Author --> [Name -once ]/[Email- unbounded]l/[Book -unbounded -->
Title/Publisher/ISBN]
Data comes from Excel

Can you give a basic code of how I should use VBA in conjunction of the
XSD file
I have access to msxml and msxml4 DLLs

Thanks a lot
Ben
