I am having some namespace related problems when using XML::Twig so once I realized that I don't know how to solve them I started posting a bug-report to its bug tracking system (see: http://rt.cpan.org/Public/Bug/Display.html?id=27617), but this was only to put the problem on the table. I then started a thread about it in israel.pm (see: http://perl.org.il/pipermail/perl/2007-July/008819.html and later posts on July 4th). Sadly, no-one on the list responded. I then tried asking on perlmonks (see: http://www.perlmonks.org/?node_id=624830)and was very happy to see that Michael Rodriguez, author of XML::Twig, took a shot to help me.
I'm now waiting for his kind help.
