REXML -- Parsing doctypes (and some some bugs)

Ruby
1

(1) How does one parse a doctype in REXML?

Hack solution –
#+++++++
require ‘rexml/document’
data =<<EOF

<?xml version="1.0" encoding="utf-8" ?> baz EOF p REXML::Document.new(data).doctype.instance_variable_get ("@long_name")[1..-2] # => "foo.dtd" #+++++++

There must be a simple solution I am missing, what is it?

(2) In rexml/dtd/elementdecl, PATTERN_RE is defined twice, issuing a
warning (see http://www.ruby-doc.org/stdlib/libdoc/rexml/rdoc/classes/
REXML/DTD/ElementDecl.html)

(3)
#+++++++
require ‘rexml/dtd/dtd’
data =<<EOF

EOF

p REXML::DTD::Parser.parse(data)

=> /opt/local/lib/ruby/1.8/rexml/dtd/elementdecl.rb:8: warning:

already initialized constant PATTERN_RE

=> /opt/local/lib/ruby/1.8/rexml/dtd/dtd.rb:25:in `parse_helper’:

undefined method `PATTERN_RE’ for REXML::DTD::ElementDecl:Class
(NoMethodError)

=> from /opt/local/lib/ruby/1.8/rexml/dtd/dtd.rb:14:in `parse’

#+++++++
