Hi David !
Would it be possible from your side to draw a detailled plan for updating to
Xerces 2 ?
Since we will have the need for Xerces 2 in Enhydra 6.0 (which will support
Tomcat 4.x and other servlet servers) we would like to do that move in XMLC.
But we can definitely need your help for outlining the detailled plan.
Please tell us what you always wanted to do...
Greetings.
Alfred

LazyDOM is the least problem when it comes integrating with Xerces 2. To
upgrade to Xerces 2, we are mostly dealing with the assumption XMLC made on
DOM interface. I have posted a long discussion in the list explaining the
problem.
"Moving XMLC to Xerces 2 won't help..."
http://xmlc.enhydra.org/project/mailingLists/xmlc/msg02059.html
We need to refactor XMLC first into the following modules and make sure
each module uses only the standard DOM Level 2 API.
- Parsing
- DOM building
- DOM editing
- DOM output
- XMLC runtime
Then, upgrading to Xerces 2 would make sense. Otherwise, simply upgrading
the DOM in XMLC to Xerces 2, we would encounter the exact same problem we
had with XMLC right now. 2.2 alpha 4 partially solves the problem of using
XMLC in a environment with Xerces 1/2 packages.

Moving to Xerces 2 is a big work and we still trying to figure out what's
the best way to do this. I can't really give a schedule at this point.
David
Am I right to think that it's a big work due to LazyDOM ? Would it be
easier to have an XMLc with xerces 2.x without the lazyDOM as a beginning
?
New optimizations could be added afterward ?
Gilles,
