Hi Maurice, That is not possible.. without adding extensions such as proposed in XQueryP or XQuery-Bang.
Why is it that running the update followed by a query is not acceptable? Another idea is to use fn:put() in the update, and then just a HTTP GET to get the XML result out. That is still a single query.
