Diff two XML doc in Ruby? [duplicate]

Answer 1

I found that was easier to use the Java library XMLUnit than any native solution

require 'java'
require '/usr/share/java/xmlunit.jar'
java_import org.custommonkey.xmlunit.Diff

puts Diff.new("", "").similar
puts Diff.new("", "").similar

Of course, this means you have to use JRuby instead of CRuby, but that wasn't a significant obstacle in my case.
