I don't think there could be any general way to generate XSLT, given the two XSDs (if that's what you are after). XSDs describe the structure of XML files, but they don’t say anything about what data they contain (their semantics, if you like).
eg.
<Customer>
<Name>ACME</Name>
<Address>9 Main Street, Anytown, USA</Address>
</Customer>
and
<Customer Name="ACME" City="Anytown" Country="USA" Address="9 Main Street"/>
- XML, , , XSD, <Address> Address, City Country .
