Optimization of XML Transformations Using Template Specialization

摘要

XSLT is the primary language for transforming and presenting XML. Effective optimization techniques for XSLT are particularly important for applications which involve high volumes of data, such as online server-side processing. This paper presents a new approach for optimizing XSLT transformations, based on the notion of template specialization. We describe a number of template specialization techniques, suitable for varying XSLT design styles and show how such specializations can be used at run time, according to user input queries. An experimental evaluation of our method is undertaken and it is shown to be particularly effective for cases with very large XML input.
