Ruby on Rails - Need to Read XML File into an Array

I am using Ruby on Rails and need to read the contents of an xml file into an array?

I pulled the data from an API using the following:

     uri = URI.parse("myAPIurl.com&show=storeID,name")
    http = Net::HTTP.new(uri.host, uri.port)
 request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)

Looking for a lean method to iterate this xml file into an array using Ruby on Rails.
