I'm working with libxml and I can't seem to define a subclass of XML::Document. For example, require 'libxml' class SubDocument < XML::Document def initialize(name) super @sub_name = name end def sub_method puts "the method" end end > s = SubDocument.new('test') => <?xml version="test"?> > s.respond_to? 'sub_method' => false > s.class => XML::Document As you can see from the above, it's as if I'm aliasing XML::Document, rather than subclassing it. I have also tried including XML and then defining the subclass as well as opening the XML module and then defining the subclass -- same results in both cases. I've never come across this before. Is there a way to fix this or should I just write my class to contain an XML::Document? Thanks, Jeremy

Hi, In message "Re: can't subclass XML::Document?" on Thu, 19 Apr 2007 22:55:08 +0900, "firstname.lastname@example.org" <email@example.com> writes: |I'm working with libxml and I can't seem to define a subclass of |XML::Document. Probably, some extensions define their own "new" class method instead of the "initialize" method. matz.
