It's easy to demonstrate that this is impossible in general. Given a schema for <p>Some <i>text</i> in italics</p> and another schema for <para>Some <italic>text</italic> in italics</para> It's clearly impossible to deduce the transformation by looking at the schemas alone. There are plenty of tools out there (generally called "mappers") that allow you to design a transformation starting from two schemas, by showing the relationships between the elements in each. They only work where the two schemas are quite similar, but that's probably true in your case. Michael Kay http://www.saxonica.com/
