Xerces2 & perl-5.8 support for XML::Xerces?

["Gerrit P. Haase" <fr...@nyckelpiga.de>]

Hello,

Xerces2 also builds on Cygwin now, we also have already a port
of perl-5.8, how is the situation with support for Xerces2 and
perl-5.8?  How works the SWIG thing, where can I find docu about
recreating the relevant parts with swig?

Yes, the renaming is for old support of operator and method
overloading. As of SWIG 1.3.14, this is all unnecessary - as
overloading is now completely supported by SWIG. The interface files
that are in the HEAD will probably only work with SWIG 1.3.13, as I
have not had time to update them.

The checkout info is at:

  http://xml.apache.org/cvs.html

the module that you want is: xml-xerces/perl

The problem I'm having is that any DOMNode that calls getFirstChild()
is returned a bogus comment node instead of the real code. I've
tracked the command execution in gdb to this line:

    result = (DOMNode *)((DOMNode const *)arg1)->getFirstChild();

at Xerces.C:23434

arg1 is a subclass of DOMNode, e.g. DOMDocument, and for some reason
the cast goes wierd and instead of winding up in
DOMDocument::getFirstChild() you wind up in
DOMImplementation::createComment().

I've tried this on PowerPC as well as i386. I haven't tried it with
gcc-3.x though, that might help.

Also, if you wanted to help update the typemaps to the latest SWIG
that would be much appreciated.

Cheers,
jas.

Yes, all my current work is committed.

I see, I have already checked out HEAD, please tell me if you committed
your latest work, I'll look then where I can help.
Meanwhile I'll build the latest SWIG release (1.3.14).

Swig is also aleady included in the Cygwin netrelease.

I read a little in the Swig manual page for Perl, when playing with
the 1.7 release I found a lot of renaming took place (in swig as well
as in Xerces), how can I checkout the HEAD branch for the perl part
to play with the recent version?  Though, I'm no C++ guru, but we have
some at the cygwin list, the will help (I hope so;)

Yes, I saw that on the xerces-c list, thanks for all that work. I have
quite a few people that want to use XML::Xerces on windows, so I would
be thrilled to have help getting it working under Cygwin!

> how is the situation with support for Xerces2 and

Perl-5.8 isn't the issue. When moving to Xerces2, I ran into a C++
problem that I haven't been able to solve, and after putting 20+ hours
of debbugging time into it, I'm not willing to revisit it without help
from a better C++ programmer.

If you, or someone else you work with, is willing to help me debug
this, I'll be happy to share the details.

  www.swig.org

There's lots of documentation on the site. If you want more
informataion, about how the XML-Xerces uses SWIG, let me know, and
I'll be happy to post the details here.
