The problem with the unwillingly shared input callbacks has been discussed a lot this year http://aspn.activestate.com/ASPN/Mail/Message/perl-xml/2069098 http://axkit.org/cgi-bin/ezmlm-cgi?5:sss:891:dbffannaclhkbkogofnc#b Steve Hay posted a patch http://aspn.activestate.com/ASPN/Mail/Message/perl-xml/2144160 similar to the one from Jason Adams http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=240334 to fix the same problem Jason's patch is part of the Debian Package now and it looks like the extra call to xmlCleanupParser() introduced by that patch resets the input callbacks AxKit still expects to be there. As Christian Glahn, maintainer of XML::LibXML points out in a comment in the source code of LibXML.xs, calling xmlInitParser() at LibXML_init_parser is the wrong way either. Which patch is now the "correct" one and which one isn't is up to the module and package maintainers I guess. What I know from everyday practice being a user of AxKit and other applications using XML::LibXML/XML::LibXSLT together in one mod_perl environment, is the fact that the globals and callbacks DO work together at versions AxKit 1.62, XML::LibXML 1.58_1 (also XML::LibXML 1.58), and XML::LibXSLT 1.57. So, why not upgrade the Debian packages libxml-libxml-perl to use XML::LibXML 1.58(_1) and libxml-libxslt-perl to use XML::LibXSLT 1.57? With that, we would have got a working setup and still can find out what is to fix at AxKit's code and look for someone to takeover the orphaned package. - --michael - -- 063A F25E B064 A98F A479 1690 78CD D023 5E2A 6688 http://zis.uibk.ac.at/.m/uibk.ac.at_pgp_pubkey.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (MingW32) iD8DBQFBd2w1eM3QI14qZogRAmgUAJ9+TjYIOna18iT1x59b/L3VNKcL2ACfTVpB 2qU85PP4v8Q+sPVdm3O+4tE= =Wp5+ -----END PGP SIGNATURE-----
