   require 'rubygems'
   require 'xml'

7. ruby test.rb

8. print error msg

Had similar problem on Windows 7x64 with libxml-ruby 2.3.3 (Ruby 2, 1.9.3 and 1.9.2). As per this solution:

https://github.com/xml4r/libxml-ruby/issues/42#issuecomment-7040881

I managed my problem was also solved. Solution (thanks to the original author):

1. Locate 'libxml.rb' in libxml-ruby gem folder (something like 'C:\Ruby\Ruby192\lib\ruby\gems\1.9.1\gems\libxml-ruby-2.3.3-x86-mingw32\lib')

2. Add the following on top of the file:

   ENV['PATH'] = ENV['PATH'] + ';' + File.expand_path(File.dirname(__FILE__) + '/libs')

3. Save and enjoy
