Write a program in Javascript that will read in an XML file. This file will contain details of devices maintained by the IT department of an organisation including an ID number, description, location, manufacturer and year purchased. The program will then ask a user whether they want to (1) list all resources displaying the manufacturer and year purchased, (2) details of description, manufacturer and year purchased for a given id or (3) list all the devices of a particular description from a particular manufacturer.
