    Locksmith precision applies to data too—just like querying XML datastores with XPath. XPath is a powerful language used to navigate and retrieve data from XML documents efficiently. With clear syntax and flexible expressions, it allows pinpoint accuracy in extracting specific elements, attributes, or values. Whether you're managing configurations or complex datasets, XPath streamlines the process. Just as a locksmith opens doors with skill, XPath unlocks structured data with precision and speed.

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

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

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

doc = Document.new xmlText

# XPath Selector for listing the titles of the last two movies in the list, listed 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[position()>=last()-1]/@title")
