RESTful thinking - Need some guidance

This is my first time working with REST and XML. My goal is to access
Google’s geocoding service using HTTP. Here’s the code I have so far:

require ‘open-uri’
require ‘rexml/document’
include REXML
url='http://maps.google.com/maps/geo?’
address = ‘q=1600 Amphitheatre Parkway Mountin View,CA’
address1 = URI.escape(address)
googleoutput = ‘&output=xml’
googlekey = ‘&key=mykey’
result=URI(url+address1+googleoutput+googlekey ).read
doc = Document.new result
r=doc.elements["/Response/Point"]
@googlresult = r.attributes[“coordinates”]

It works up till this line doc = Document.new result (I’m using IRB to
test this BTW)

It says undefined when that line is executed. Having never done this
before, I don’t know what the issue is. I also know there is a
google-geocode gem but I’m trying to understand this so I can customize
it a little.

Here’s a sample of the XML output:
http://www.google.com/apis/maps/documentation/#Geocoding_HTTP_Request

I need to get the status code and the coordinates.

Any help is greatly appreciated.

Thanks for the help! I was able to figure it out with that tutorial and
looking at the google-geocode.rb file from the gem.

Here’s what I came up with

url=‘http://maps.google.com/maps/geo?’
address = ‘q=1600 Amphitheatre Pkwy, Mountain View, CA’
address1 = URI.escape(address)
googleoutput = ‘&output=xml’
googlekey = ‘&key=mykey’
result=URI(url+address1+googleoutput+googlekey ).read
doc = Document.new(result)
root = doc.root
coordinates =
root.elements[’/kml/Response/Placemark/Point/coordinates’].text
long, lat, = coordinates.split(’,’).map { |v| v.to_f }
