So Miles, if you prefer the occasional synchronization issue to the routine method invocation overhead, use a parser that obliges you. (Yes, I'm assuming SAX2 doesn't mandate any interning, just exposes whether or not it's done.) Though I daresay you'll find that the synchronization isn't usually measurable, while your evidently preferred alternative (lots of String.equals calls) will consistently show up as a performance problem. At least that's been the case when I've made such measurements. - Dave xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
