After weeks of scouring the newsgroups and Googling, and much experimentation, we remain absolutely perplexed as to how to get better Xpath performance from Xalan (mostly in selectSingleNode and selectNodeList operations). In our case, the source will always be a Xerces DOM.
We're experiencing a roughly 10X-20X degradation in performance relative to comparable code using the Microsoft Xpath evaluation functions in .NET. We're about to consider trying Dom4J or JDOM just to see if we can get some better performance, but we'd hate to give up now. We have tried CachedXPathAPI, but its usage is quite unclear (and how the DOM/DTM gets cached is still unclear). Low level API's are certainly an option, but we're in the dark as to appropriate usage. Consider this a plea for help and guidance!
