Programming with XQuery

XQuery is a declarative language for querying and updating XML data sources. Interfacing XQuery to a host programming language is difficult because of the type system mismatch, and global optimization is difficult in a mixed-language environment. In this paper, we investigate a small extension called XQueryP that enables XQuery expressions to exchange state information through variables. This extension makes it easier to develop applications in XQuery without relying on a host programming language. We draw an analogy between the proposed extension and similar extensions that have been added over the years to the SQL query language for similar reasons.
