How easy this is depends very much on how complicated your schema is -- using named model groups, included schemas and (worse!) redefined schemas makes life really difficult. What you have to do is navigate through the schema and the instance document side-by-side. I wrote up how to do this in detail in my chapter for Professional XML Schemas from Wrox: http://www.amazon.com/exec/obidos/tg/detail/-/1861005474 There it was for the purposes of filling in an HTML form, generated from the schema, within information from an instance document, but the same principles apply. Unfortunately, it's rather involved, so all I can suggest is that you buy, borrow or steal the book, or contact me offline and I'll send you the source code if you'd like.
