Bear with me, please, a little more hand-holding and I may be
able to start contributing rather than draining.
I have some DTDs that use Xlinks, even though the xlink specification
is still coming and no XSLT supports it without help. The existance
of DOMParser::setDoNamespaces in Xerces C++ made me hopeful that
markup with names like xxx:foo would work in Xerces Perl. But when
I include xlinks in my DTD, Xerces-perl seems to be dumping core
(unless I am doing something wrong, which is quite likely).
I attach minimal dtd and xml files that cause the core dump
(at least in my configuration) with the perl (also included)
that I am using to parse it. Should I give up on xlinks or
am I making a mistake?
Thank you for your patience, and thank you.
Juan
Fixed! (was Re: Namespaces)

I'm not sure why I thought I should turn on namespaces...
~/work/xml-xerces/perl $ perl ./samples/DOMCount.pl -v ./test.xml
./test.xml: (1 elems)
So whatever problem there was seems to have been fixed.

Hey Juan,
After tracking down the awful error handler bug I finally got some
cycles to test your code again. This is what I get from
XML-Xerces-1.3.3:
~/work/xml-xerces/perl $ perl samples/DOMCount.pl -v -n ./test.xml
FATAL ERROR:
LINE: 10
COLUMN: 2
MESSAGE: An exception occured! Type:IllegalArgumentException, Message:String pool id was not legal
I added the -n (namespace) flag to DOMCount.pl hoping it would help,
and we get a little further, but I'm not sure what the string pool ID
problem is coming from.

Thanks for your reply. I will try to replicate the core
dump problem in xerces-c 1.4 and go to those guys with the
story if I succeed. If, whenever you have a chance, you can
confirm that the problem as it appears in xerces-p is not due
to something local to me, I would be indebted. But no rush.
Thanks for all your work.
Juan

OK. That's a good point. I'm using a dynamic lib of xerces-c1_3 that I
compliled off the CVS tree a while back, and I haven't tried compiling
off the xerces-c1_4.
I should download the Xerces-C-1.3 official tarball and compile
against that before we make an 'official' release of Xerces.pm

I have only used the latter. I actually don't know much about what all
the different options will buy me :-(
But still nothing looks problematic so far.

This all looks fine, except that you are running on x86 and I'm
running on PPC. I believe Harmon has x86 at his place, so this
shouldn't be an issue. What distribution are you running (I'm running
debian).
Let me work on merging the SWIG 1.3 and HEAD branches, and then I'll
compile it on my x86 box, and let you know what I find. Sorry I can't
be more helpful at this point. Stay patient and we'll solve it soon.

Thanks again Jason,
I have now tried xerces-c1.4 and xerces-c1.3, Harmon's tarball as
well as the cvs main line (swig 1.1) as of 9 March 11:00 EST. The
following compile but dump core on the file with namespaces:
xerces-c1.4 w/ Harmon's tarball
xerces-c1.4 w/ cvs xerces-p
The following causes a run-time error because, apparantly, xerces-c1_3
does not define BinInputStream (needed by xerces-p) so the DynLoader
fails to load Xerces.so:
xerces-c1.3 w/ cvs xerces-p
I haven't tried:
xerces-c1.3 w/ Harmon's tarball
My perl and your perl are similar. I think the problem must be in the
way I have compiled xerces-c. I have tried compiling it with
./runConfigure -plinux -cgcc -xg++ -minmem -tnative -nsocket
as well as with
./runConfigure -plinux -cgcc -xg++ -minmem -tnative -nfileonly
Does this look like a problem to you all?
(I include my perl -V output as requested)
Many thanks, again.
Juan

Hey Juan,
I don't see this at all. This is what I get:
~/work/xml-xerces/perl $ perl -Mblib ./parsexml.pl
Using /home/jasons/work/xml-xerces/perl/blib
FATAL ERROR:

Looking at your code, it seems your using Harmon's tarball and not the
CVS code. I would update to the code I checked in to CVS, or at least
grab the latest tarball I put up an hour ago.
If you still have trouble, write again and include the output of perl -V, and
I'll see what's up.
I've included the output of my 'perl -V' below.
