Two Implementations of XPointer

摘要

We report on two different projects being developed at the University of Bologna, both of which make use of the new XPointer language, for which two different implementations were deemed necessary. The first project is an HTTP proxy for providing external linkbases expressed in XLink. The second is an extension to XSLT to express transformations on string patterns as well as node patterns. Both libraries have been implemented with ease and efficiency, demonstrating the usefulness and reasonableness of the language.
