Re: Assembly-language XML parser
Thanks for the note, Rick. But on the topic of points for bravery, we're now trying to avoid that, by hiding the low-level parallel bit stream and SIMD programming details using compiler technology. Our goal is to broaden the applicability of the techniques well beyond XML. This approach is the crux of our Parabix 2 effort. At Balisage '09 we presented the basic bistream equations and concepts. Subsequently, we have developed a high-level Python prototyping technique and our first prototype compiler, completed this summer. Of course, this is still a research effort and the XML community may be more interested in practical parsers. On that note, we have now switched emphasis from development of a standalone Parabix parser to development of accelerated versions of existing tools (Xerces, Saxon, etc.). To check out our research code and xmlwf sample application (for DTDless XML), use the following steps (Linux). (1) svn co http://parabix.costar.sfu.ca/svn/proto (2) Change to the parabix2 prototype directory and compile to generate C code. cd proto/parabix2 make (3) Change to the src subdirectory and compile the C code. cd src make You'll need an SSE 4.1 machine to run the xmlwf application. (4) Test the application against the W3C XML conformance suite (DTDless subset). make test Robert D.
