    # Standard ruby library for XML parsing
require 'rexml/document'
include REXML

# Enter your code here. Read input from STDIN. Print output to STDOUT
xmlText = "movies.xml" 

# Read the input XML Fragment
while line = gets()
	xmlText += line
end

doc = Document.new xmlText

# XPath Selector for listing the titles of the movies, in the same order as which they occur in the given XML.
# Fill in the blanks to complete the required XPath selector query
puts doc.elements.each("collection/movie/@title")
