# frozen_string_literal: false #vim:ts=2 sw=2 noexpandtab: require_relative 'child' require_relative 'source' module REXML # This class needs: # * Documentation # * Work! Not all types of attlists are intelligently parsed, so we just # spew back out what we get in. This works, but it would be better if # we formatted the output ourselves. # # AttlistDecls provide *just* enough support to allow namespace # declarations. If you need some sort of generalized support, or have an # interesting idea about how to map the hideous, terrible design of DTD # AttlistDecls onto an intuitive Ruby interface, let me know. I'm desperate # for anything to make DTDs more palateable. class AttlistDecl < Child include Enumerable # What is this? Got me. attr_reader :element_name # Create an AttlistDecl, pulling the information from a Source. Notice # that this isn't very convenient; to create an AttlistDecl, you basically # have to format it yourself, and then have the initializer parse it. # Sorry, but for the foreseeable future, DTD support in REXML is pretty # weak on convenience.
