Creating XSD from XML data

why do you want to create it automatically

IMO you'll find less problems doing it yourself based on a spec than hoping that the XML file your trying to base it on contains all the correct data

Yep I agree, in fact that is what I suggested -- it's for another team here.

They just want to use the data to create the bulk of the structure, and fill in the blanks so to say.

Looks like you can create the DTD from the XMlL, but there's no mention of the XSD.

I'll take a look in more detail - thanks.

How can you ever expect the XSD produced to be useful?

Optional elements and attributes, field lengths, patterns (regex), sequence, unions, referenced types, namespaces, and lots and lots more are in the XSD that can never be "inferred" by one or more XML instances.

Madness.

he mentioned using it as a starting point, nothing more...

**ChimpMaster** · 15 February 2007, 13:33

Yep that's right, just a starting point -- and God knows if they only want it for "documentational" purposes, i.e. never to be seen again!

Thanks again.

.NET can do it. At least it claims to. Never tried it in anger.
