xml - Ruby Hash parsed_response error -

background

i using httparty parse xml hash response. unfortunately, when hash response has 1 entry(?), resulting hash not indexable. have confirmed resulting xml syntax same single , multiple entry(?). have confirmed code works when there multiple entries(?) in hash.

question

how accommodate single hash entry case and/or there easier way accomplish trying do?

code

require 'httparty' class rest include httparty format :xml end def test_redeye # rooms , devices roomid = hash.new deviceid = hash.new { |h,k| h[k] = hash.new } rooms = rest.get(@reip["theater"] + "/redeye/rooms/").parsed_response["rooms"] puts "rooms #{rooms}" rooms["room"].each |room| puts "room #{room}" roomid[room["name"].downcase.strip] = "/redeye/rooms/" + room["roomid"] puts "roomid #{roomid}" devices = rest.get(@reip["theater"] + roomid[room["name"].downcase.strip] + "/devices/").parsed_response["devices"] puts "devices #{devices}" devices["device"].each |device| puts "device #{device}" deviceid[room["name"].downcase.strip][device["displayname"].downcase.strip] = "/devices/" + device["deviceid"] puts "deviceid #{deviceid}" end end "done" end

xml - single entry

<?xml version="1.0" encoding="utf-8" ?> <devices> <device manufacturername="philips" description="" porttype="infrared" devicetype="0" modelname="" displayname="tv" deviceid="82" /> </devices>

xml - multiple entry

<?xml version="1.0" encoding="utf-8" ?> <devices> <device manufacturername="denon" description="" porttype="infrared" devicetype="6" modelname="avr-3311ci" displayname="avr" deviceid="77" /> <device manufacturername="philips" description="" porttype="infrared" devicetype="0" modelname="" displayname="tv" deviceid="82" /> </devices>

resulting error

there couple of options see. if command endpoint, modify xml beingness sent accomodate httparty's underlying xml parser, crack putting type="array" attribute on devices xml element.

otherwise, check see class device before indexing it:

case devices["device"] when array # deed on collection else # deed on single element end

it's much less ideal whenever have type-checking in dynamic language, if find doing more 1 time may worth introducing polymorphism or @ to the lowest degree extracting method this.
