# Calling #to_hash on the Savon response in earlier version of Savon (0.8.6) return namespace keys formatted 
# as such: :type, :ns14, :xsi. But in Savon 1.0.0, #to_hash returns namespace keys like :"@xsi:type", 
# :"@xmlns:ns14", and :"@xmlns:xsi". This broke some parsing logic we had set up for the hashed Savon response.

# To change the format of these tags (or any tag, for that matter) in the hashed response, 
# you can configure Nori like so:

Nori.configure do |config|
  config.convert_tags_to do |tag|
    converted_tag = tag[0] == "@" ? (tag.split(":")[1] || tag[1..-1]) : tag
