    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

    Write the XPath selector for finding the number of characters (i.e, the string-length) in the description of the second movie in the XML file.

    Fill in the blanks to complete the required XPath selector query

    description = doc.elements["/collection/movie[2]/description"].text puts description.length
