Hi all,   I have just tried 3 parsers, Xerces Java 1, Xerce Java 2 and Crimson, use both DOM and SAX parser parse a 960kb XML file for 10 times, the time cost are:              Xerces 1        Xerces 2      Crimson DOM     3906               4937            4697 SAX      1322               1832            1332   It is said that my best choose is Xerces1. So, what's the improves in Xerces 2?
