Summary: XML::Reader does not work with sockets

Initial Comment:
I tried with the two following programs:
A server:
#!/usr/bin/ruby -w

require 'rubygems'
require 'xml'
require 'socket'


server = TCPServer.new(22222)
while session = server.accept
  reader = XML::Reader.io(session)
  loop do
    rsl = reader.read
    puts rsl
    break if rsl != 1
    puts reader.expand
  end
  session.puts 'ok'
  sleep 1
  session.close
end
# end-of-server
and a client:
#!/usr/bin/ruby

require 'socket'

t = TCPSocket.new('localhost', 22222)

t.puts '<doc><a>k</a></doc>'
puts t.gets
# end-of-client

Output from server:
Entity: line 1:
parser
error :

I tried different platforms (RH9, CentOS 5.1 and Fedora8).
libxml-ruby-0.8.3
Various libxml2 versions

Message:
I wouldn't know where to begin. Before I tried I had a look
at the code, ruby_xml_reader_new_io(int argc, VALUE *argv,
VALUE self), and had the strong impression that it _was_
implemented.
I have no idea what is missing.
C and ruby extensions are by no means my strong suit, I
prefer ruby <g>.
My C is read-only, with the exception of the occasional
small patch

Message:
Yes, that is not going to work.  Libxml does provide its own socket implementation, but that is not exposed via the ruby bindings.  Want to put together a patch?
