The presence of a formfeed character, aka "\f", aka chr(12), seems to disrupt parsing in XML::Twig 3.13 . test case: $ perl -MXML::Twig -le'XML::Twig::Elt->parse("<xml></xml>")' #fine $ perl -MXML::Twig -le'XML::Twig::Elt->parse("<xml>\n</xml>")' #fine $ perl -MXML::Twig -le'XML::Twig::Elt->parse("<xml>\r</xml>")' #fine $ perl -MXML::Twig -le'XML::Twig::Elt->parse("<xml>\f</xml>")' #breaks not well-formed (invalid token) at line 1, column 5, byte 5 at /usr/lib64/perl5/vendor_perl/5.8.5/x86_64-linux-thread-multi/XML/Parser.pm line 187 $ perl -v This is perl, v5.8.5 built for x86_64-linux-thread-multi $ uname -a Linux {machine name} 2.6.9-42.ELlargesmp #1 SMP Tue Aug 15 11:42:23 BST 2006 x86_64 x86_64 x86_64 GNU/Linux Adam

This is not an XML::Twig problem. The parser (expat) complains because form feed is not a valid character in XML (see the spec, for example at http://www.xml.com/axml/target.html#dt-character : #xC is not part of the character range). -- mirod
