Alexandre Brillant has released FastParser 1.6.4, a $50 shareware, non-validating, XML parser for Java that supports SAX and some of DOM. Version 1.6.4 fixes various bugs. Brillant claims this parser is faster than Xerces, but his benchmarks only test one file; and it's not clear from his result whether FastParser was used in a mode that doesn't perform full well-formedness checking.
