What's wrong with this code?

I'm trying to interface with the flickr API to pull my photos into my
site. I don't want to use the "flickr.rb" gem, I'd like to do it the
other way so I can learn (plus I had trouble loading the gem on my
server). Anyway, here's what I have:

#Application.rb controller

    def get_response(path, http)
      request = Net::HTTP::Get.new(path)
      response = http.request(request)
      response.value
      response.body
    end

path =
"/services/rest/?api_key=API_KEY&method=flickr.photos.search&user_id=USER_ID&tags=TAG"
http = Net::HTTP.new('flickr.com')

    @photo_ids = Array.new
    http.start do |http|
      xml = get_response(path, http)
      REXML::Document.new(xml).root.get_elements('photo').each do

photo>

        id = photo.attributes['id']
        @photo_ids << id
      end
    end

#Application.rhtml layout

<% for p in @photo_ids %>
<%= p %>
<% end %>

This just doesn't do anything. It doesn't give me errors, but it the
@photo_ids variable is empty. I've also tried <%= p.id %> and so on.

Can someone see something wrong with this code? Thanks!

>photo>

I don't know if this gives you every photo or not. I think the path is wrong.

        id = photo.attributes['id']
        @photo_ids << id
      end
    end

#Application.rhtml layout

<% for p in @photo_ids %>
  <%= p %>

The easiest way to do this is to use OpenURI.

$ cat x.rb require 'open-uri'
require 'rexml/document'

api_key = ARGV.shift
user_id = ARGV.shift
tag = ARGV.shift

uri = "http://flickr.com/services/rest/?api_key=#{api_key}&method=flickr.photos.search&user_id=#{user_id}&tags=#{tag\}"

open uri do |res|
   xml = REXML::Document.new res.read
   xml.elements['/rsp/photos'].each_element do |photo|
     photo_id = photo.attributes['id']
     server = photo.attributes['server']
     secret = photo.attributes['secret']

PS: Matz has ridden in that car.
