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.

For simple use cases you can use:
xml = <<-XML
<?xml version="1.0" encoding="UTF-8"?>
<hash>
<foo type="integer">1</foo>
<bar type="integer">2</bar>
</hash>
XML
hash = Hash.from_xml(xml)
# => {"hash"=>{"foo"=>1, "bar"=>2}}
Hash - Ruby on Rails

Try using Nokogiri gem. It's super easy to use, the website has some nice examples.
require 'open-uri'
doc = Nokogiri::HTML(open("myAPIurl.com&show=storeID,name"))
you can then query your document using xpath or css selectors. It then returns a NodeSet that you can iterate over like you would do with an array
Hope it helps

Rails: ActiveSupport JSON parse ill-formatted JSON

The response I get is
page_play_model_exponentModel__getNum({"code":1,"message":"","result":{"icode":"JXdywDcV0hA","totalVv":6}})
This is not a typical JSON response. So when I use activesupport like
decode_response = ActiveSupport::JSON.decode(response), it will report
JSON::ParserError: 795: unexpected token at 'page_play_model_exponentModel__getN
um({"code":1,"message":"","result":{"icode":"JXdywDcV0hA","totalVv":6}})
'
How can I parse this properly? I want the totalVv value and I can get it ugly,
like
totalVv = response.split("'totalVv':")[1].split("}")[0], but this is just weird.

It looks like a JSONP response, but you could use a regex to extract the JSON
response = 'page_play_model_exponentModel__getNum({"code":1,"message":"","result":{"icode":"JXdywDcV0hA","totalVv":6}})'
json = /(\{.*\})/.match().to_s

Rails/Ruby equivalent of PHP file_get_contents

Would like to know the Rails/Ruby equivalent of the following PHP:
$data = json_decode(file_get_contents(URL_GOES_HERE))
The URL is an external resource that returns json data (Facebook's API).
I've tried:
data = JSON.parse(URL_GOES_HERE)
but I assume I still need the `file_get_contents' part? How do I do this in Rails 4?

Try this
require 'open-uri'
file = open(URL_GOES_HERE)
data = JSON.parse file.read

Rails: How to send a http get request with UTF-8 encoding

I'm trying to use an external API to get some information
address=self.address
response = HTTParty.get("http://api.map.baidu.com/geocoder/v2/?address=#{address}&output=json&ak=5dfe24c4762c0370324d273bc231f45a")
decode_response = ActiveSupport::JSON.decode(response)
However, the address is in chinese, so I need to convert into UTF-8 code,
if not I'll get URI::InvalidURIError (bad URI(is not URI?): How to do it?
I tried address=self.address.force_encoding('utf-8'), but it does not work, maybe I should use other method instead?
UPDATE:
uri = "http://api.map.baidu.com/geocoder/v2/?address=#{address}&output=json&ak=5dfe24c4762c0370324d273bc231f45a"
encoded_uri = URI::encode(uri)
response = HTTParty.get(encoded_uri)
decode_response = ActiveSupport::JSON.decode(response)
self.latitude = decode_response['result']['location']['lat']
and I get can't convert HTTParty::Response into String. What's wrong with it?
I found something here, I think I'll need to tell Httparty explicityly to parse it with JSON?

You could save this to a file 'geo.rb' and run ruby geo.rb
require 'uri'
require 'httparty'
address = "中国上海"
uri = "http://api.map.baidu.com/geocoder/v2/?address=#{address}&output=json&ak=5dfe24c4762c0370324d273bc231f45a"
encoded_uri = URI::encode uri
puts HTTParty.get(encoded_uri)

743: unexpected token at '... in Ruby on Rails

I saved a file named array.json on my Dropbox folder and i access to it via Dropbox API. All works fine, but when i retrieve JSON content i cannot JSON.parse that string!!
session = DropboxSession.new(APP_KEY, APP_SECRET)
session.set_access_token(ACCESS_TOKEN_KEY, ACCESS_TOKEN_SECRET)
client = DropboxClient.new(session, ACCESS_TYPE)
json = client.get_file(DIRECTORY + '/array.json')
#json = JSON.parse json
Error:
743: unexpected token at '{"Nome" : "Mario Rossi",
"C.F." : "ABCDEFGHILMNOP",
"Booking Assistance" : "MARIO",
"Status of reservation" : "25/11/2011"}'
JSON string is valid!! if i copy this string and paste it (manually) as parameter in JSON.parse(), json is parsed correctly!! So i think is a encoding problem...but where i wrong?

We have abandoned the json parsing backend that is the default in Rails. The default backend is YAML based and imo a useless mess. After several gotchas parsing unicode, and dates in some cases, we discovered that the backend can be replaced via configuration.
You can substitute the parsing backend in an initializer
ActiveSupport::JSON.backend = "JSONGem"
There are several gems that can be used as the backend, we just use the json gem
gem 'json'
