Try this: http://codeviewer.org/view/code:2c08 (sorry, but code posted 
on usenet looks really ugly). Note that this code can only handle a 
schema that looks like the one you have provided (no support for 
xsd:choice, schema must be in Russian Doll format, no proper quoting of 
special characters like <>" which are not allowed in XML string).
