Re: [xml-dev] Generating XML from XSD

It's already been mentioned that tools like XMLSpy">XMLSpy and oXygen have some  
capability to produce XML instances to match a Schema.  However, my own  
experience (mostly with users who had XMLSpy">XMLSpy) is that the tool often  
generated invalid instances, and the users then assumed that there was an  
error in the Schema that they had been given.

In particular, I'm not sure if any tool will reliably generate valid  
instances if there are pattern restrictions in a Schema.  This may well be  
an intractable problem, to generate a valid string match a pattern for any  
arbitrary pattern.  Certainly it isn't a trivial problem.  It does mean,  
however, that you should never expect an XML instance generator to fully  
valid XML.  It may need editing to make it valid.

Cheers, Tony.
