Hi guys:)
I'm developing a j2ee development descriptor editor. I parse xml file
with apache digester, It needs Xerces. It takes me about 1.6sec to parse a
big ejb-jar.xml(it has 1024 <entity>s) on eclipse 2.1.3. When I update my
plug-in on eclipse3.0, It takes me about 4sec to do it. I read the release
note, eclipse3.0 remove xerces packake. Is it a reason?
How can I low the parsing time? thank you very much.

The Sun JDK 1.4.* includes XML parsing support (the Crimson implementation)
and this was one of the reasons to no longer provide Xerces with Eclipse.
There are differences between the Crimson and the Xerces implementations
which both conform to the JAXP (Java API for XML processing)
You have many choices including providing and using Xerces yourself.
As well you could see why the parsing is slower using the Crimson parser and
see if you can make adjustments to correct the slowdown.
BTW I believe JDK 1.5.* has moved back to using some incarnation of the
Xerces implementation.
IBM JDKs 1.4.* use some incarnation of the Xerces implementation.
All very confusing :-)
