You may be able to produce what you want by defining a module and
extending the Document with it:
ardent:~ danj$ irb
irb(main):001:0> class A
irb(main):002:1> end
=> nil
irb(main):003:0> module B
irb(main):004:1> def hello
irb(main):005:2> puts "hello"
irb(main):006:2> end
irb(main):007:1> end
=> nil
irb(main):008:0> a=A.new
=> #<A:0x19256c>
irb(main):009:0> a.extend B
=> #<A:0x19256c>
irb(main):010:0> a.hello
hello
=> nil
irb(main):011:0>
You can also override #parse by renaming the original function and
perform the extend after calling #parse_original.

I'd like to create a subclass of XML::Document. However, I'm having
trouble figuring out how I would instantiate my subclass because
parsing requires Parser.parse() which returns an XML::Document
instead of My::Subclass. Unfortunately, Ruby doesn't have a way of
changing the class of an object.
Any suggestions?
