Xerces 2
Kimbro/Tom,
Any plans to do the first release using Xerces 2?

Mark

Should this question go to the users list, then?
I'd like to see Xerces2, because it has better schema support, and it is more forward
looking. The Apache Xerces home page had been recommending moving to
Xerces2 because it was replacing Xerces1 and that Xerces1 was to become a dead
project, but I can no longer find this, so I wonder if they are backing off from retiring it
right away. (Anyone have the dirt on this?)

I've used XNI to implement a pull parser for my employer. It's very
well designed. As far as Xindice's concerned, it would be better if we
could be JAXP bootstrapped wherever possible so that we're not tied to
any one XML parser.

Would there be any benefit to moving Xindice to use the XNI interfaces of
Xerces2? I haven't really looked at XNI yet, but it's a thought.

It is faster. I use it in a lot of our code here at the University and it
seems to be about 20-30% faster.

The StringBuffer will become slower as the document size increases (I've
tried this approach to, it was unhappy with a 150MB XML document)

Look here. The Electric Mind SAX parser is VERY fast.

I switched from JDom to dom4j a month or so ago and had very appreciable
performance improvements. No formal testing, but observation indicated almost
two fold. Note, however, that I do very heavy processing once the documents
are retrieved, so your mileage may vary.

The majority of internet users are still using 56k modems... Sad but
true. For quite a while after moving to Arizona, I couldn't get cable
modem or DSL service in my area, and was stuck using 56k, or doing all
of my high-traffic transfers when I was at work.

56k, are you thinking that "Neanderthal Man" will be downloading
Xindice ;-)?

There are different factors to consider. Xindice will only parse a
document as it's going into the system, and it will use the
JAXP-available SAX parser to do that, which is where the speed of the
SAX parser will make a difference. Beyond that though, it uses the
Xindice DOM implementation, so the only way to improve performance in
that scenario is to optimize the DOM impl.

I'm thinking more for people who are downloading it over a 56k line.
We're close to 5 megs at this point without Xerces 2.

I believe I saw an message that said it was faster...
I haven't done any comparisons. Also, it is a
complete rewrite, so it might be safer to stick
with one that works...
I want speed ;-). I am using the sax parser for some of
my internal parsing and JDom for creating some of the
documents. I will probably stop using JDom because I
think it is faster to create documents through StringBuffer :-).
I suppose that I could try and find a faster SAX parser...
As far as the size of the distribution goes, I am installing from
a CD, so I don't think space is an issue.
thanks,
Mark

Dunno. Xindice works with Xerces 2 from all outward indications, and
Sun has it operating against the Xerces 2 jars in their web services
developer pack, but my leaning is to keep the smaller Jar just to keep
the distribution small. Overall, makes no difference to me, and I guess
depends on what the users want.
So.... What do you want?

I don't want to change anything else. I just want to ship it. We've been
sitting on this 1.0 for months, it needs to be released so we can put it
behind us and move on. In my opinion, as soon as we get 1.0 out then we
move all the jars to the latest versions for the next release. If someone
really wants Xerces 2 they can just replace it in their build. I'm really
hoping we can get a 1.1 or something out within a few weeks of 1.0, but
right now we're stalled and 1.0 needs to go out the door warts and all.
