I've had good results on this using Stylus Studio. It works from a single
instance document, but you can always combine multiple instances into one
before you start. There is some control over the design patterns it uses,
but I generally find the default settings are quite usable. Of course you
have to tidy up the generated schema by hand afterwards, for example to make
intelligent decisions about when to use enumerations and patterns in your
simple types, or when to impose a hierarchy of types or substitution groups,
but I find it's often a good way of creating a first cut.

Subject: Tools to Generate XSD from Sample Instances


I am wondering if there are good tools that would enable (auto) generation
of XML schema from multiple instances of sample XML document.
 
It seems to me that one should be able to specify certain parameters for the
resulting schema, e.g., the design pattern [1] to be followed.
 
Any comments or suggestions?
