Basic Question on Creating XML documents

[vvenk]

Hello:

I am learning XML technology. I have a question on creating an XML document
that conforms to a DTD/XSD.

While there is a function that I can call to make sure that the XML document
is valid, I would like to know how I can create it.

Do I have to understand the DTD/XSD and code my module so that the XML
document is valid? Or, are there tools available to do this? What if the data
is in SQL Server but I have to create an XML rendition of the data that
conforms to a DTD/XSD?

Thanks.

Yes.

Yes, any good XML editor can read a DTD or Schema and let you create
a valid initial document by hand to get started with. That will help
you understand the data structure, so then coding will be much easier.

You need to understand the data structure of the database *and* the target
DTD/XSD first, then you will see more clearly what mapping you need.
Beware: there is rarely a perfect 1:1 mapping :-)
