The Formal Semantics of XQuery Language

Yang Hong

Abstract

XQuery language is used to search XML document. The specification of the language is W3C working draft now. The formal semantics will help to the standization of the language. This paper models the semantics of XQuery language by reusing the common semantic construct of XML family languages. The presentation of semantics uses formal specification language Object-Z notation. This object-oriented description is not only concise. extensible and composable.but also consistency between specifications.
