Title: XPath -> SQL

I noticed in the list archives that there was some discussion last year about converting XPath expressions to SQL queries. Specifically, my interest would be to take a relational schema that has been generated from an XML schema of some flavor, and map XPath expressions based on the XML schema into SQL queries based on the corresponding (i.e. generated) RDBMS schema. Does anyone know of any work that has been done or is being done in this area?

Thanks in advance for any pointers,
Matthew
