Abstract

In this paper, we present the design and implementation of a filtering approach for XML documents which is based on XPath expressions and Aspect-Oriented Programming (AOP). The class of XPath expressions used allows for branching, wildcards and descendant relationships between nodes. For the embedding of simple paths into XPath expressions, a dynamic programming approach is proposed. The AOP paradigm, which provides a means for encapsulating crosscutting concerns in software, is introduced to integrate the filtering approach in the broader context of event-based parsing of XML documents using SAX.
