So I created my own subclass of REXML::Document. Like this:
#begin example
class MyDoc < REXML::Document
def initialize () @tree = super("")
puts @tree.class @name = tree.root.add_element(“test”)
end #end example
The above results in “undefined method `root’ for nil:NilClass
(NoMethodError)”
Also trying ‘super.new("")’ doesnt work.
I can get it working by writing @tree =
REXML::Document(""), but then my nice class will only be a
container, not a subclass.
How can I actually get it working? Ie. get my very own subclass of
REXML::Document with my very own initialize.
Yes, its a foggy day and inheritance seems to escape me…

try this:
-----BEGIN PROGRAM-----

xml =<<END_DOC
END_DOC
class MyDoc < REXML::Document
def initialize (fnm)
super(fnm)
puts “from initialize: #{self.class}” @name = self.root.add_element(“test”)
