I'm not overly familiar with xpath, so I can't really tell you how to do this, but it should be doable. You might want to look into REXML.

please try this-

#!/usr/bin/ruby -w
 
require 'rexml/document'
include REXML
 
xmlfile = File.new("movies.xml")
xmldoc = Document.new(xmlfile)
 
# Info for the first movie found
movie = XPath.first(xmldoc, "//movie")
p movie
 
# Print out all the movie types
XPath.each(xmldoc, "//type") { |e| puts e.text }
 
# Get an array of all of the movie formats.
names = XPath.match(xmldoc, "//format").map {|x| x.text }
p names
 

this will yield the following result

<movie title='Enemy Behind'> ... </>
