XML Querying Using Data Logic Structures and Primitives

There have been several proposals for transforming and querying XML structures, but very few of them offer a data logic approach. This article describes data structures and some primitives as a framework to efficiently manipulate XML well-formed documents. The implementation of the querying system, based on the proposed framework, is performed in the Prolog programming language. Results indicate that this approach allows the solution of both deductive and recursive queries from XML documents.
