Thanks to the folks from Sun for all their hard work in making this happen! Now we have some work to do! :-)
The xml-contrib area is designed so that people can look at the code, try it out, etc. The license issues have all been worked out, and the code is now under the Apache 1.1 license, so feel free to look at it, play with it, figure it out, etc. I have a couple of major suggestions (I'm sure that other people have more): 1) It has been reported that the Crimson code is 50% faster than Xerces-J when running on a Sparc Ultra-5, however Xerces-J is 40% faster than Crimson on a Windows NT machine. It's not obvious to me why this would be true! We need to figure out WHY, so we can create a single code base that is fast on BOTH. 2) Crimson has a DOM implementation that is particularly interesting. It has been reported that it "scales better" as the size of an XML document goes up, but that is not my experience (but, I've been looking only at Windows NT, so this could again be a Sparc/Windows difference). This could be due to differences in memory consumption, or something else altogether. We should be able to figure out what's going on here, and get the best of both worlds. Because the Xerces DOM is pluggable, we might need to end up with two DOM's that are optimized for two different things: a) the current deferred DOM is optimized for performance, but maybe not for memory consumption, and b) perhaps the Crimson DOM is optimized for memory consumption. 3) Now that we can see the XHTML code, we should be able to compare Assaf's HTML parser code, and the new Crimson code, so we can end up with the best of both. We routinely get requests for HTML parsing, and this is a pretty self-contained area, so it's a great opportunity to jump in and contribute! All of these things are high on my list -- does anybody want to take a crack at them? This is a great opportunity for some new people to jump in, and check out all the code... Mike P.S. Traffic is now moving to the xerces-j list...please adjust your mailing list subscriptions accordingly!
