Thanks for your reply.
But I am afraid that it works only in rails console, not in irb console.
This is because to_xml method is defined inside ActiveSupport of rails.
But I want pure ruby code to convert to xml.

Actually in my case, array is the collection of objects. And object is 
basically collection of hashes. Finally I made it own using REXML.
