I am trying to build a library of pull parser based mixins for
LibXML::XML::Reader and rexml/pull_parser but I cannot subclass
LibXML::XML::Reader and get this mixins included. How can I do this without
reopening LibXML::XML::Reader?
for instance: this doesn't work
require 'libxml'
module Helpers
def testing
'this should work'
end
end
class SimpleReader < LibXML::XML::Reader
include Helpers
end
if $0 == __FILE__
reader = SimpleReader.string('<testing><node></node></testing')
puts reader.testing
end
>> C:\Documents and Settings\dominic e sisneros\My
Documents\programming\ruby\simple_reader\spec>ruby include_test.rb
include_test.rb:21: undefined method `testing' for
#<LibXML::XML::Reader:0x2dfb2c0> (NoMethodError)
but if I do
module LibXML
module XML
class Reader
include Helpers
end
end
end
it works
