How to send Twilio SMS

class MessagesController < ApplicationController

require 'twiliolib'
require 'rexml/document'
include REXML

    # Twilio REST API version
    API_VERSION = '2008-08-01'

    # Twilio AccountSid and AuthToken
    ACCOUNT_SID = 'ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
    ACCOUNT_TOKEN = 'xxxxxxxxxxxxxxxxxxxxxxxxxx'

   def create
    @message = Message.new(params[:message])

    # Create a Twilio REST account object using your Twilio account ID and token
    account = Twilio::RestAccount.new(ACCOUNT_SID, ACCOUNT_TOKEN)

    d = { 'From' => @message.From, 'To' => @message.To, 'Body' => @message.Body }

    resp = account.request("/#{API_VERSION}/Accounts/#{ACCOUNT_SID}/SMS/Messages", 'POST', d)
    resp.error! unless resp.kind_of? Net::HTTPSuccess

    h = Document.new resp.body

    s = XPath.first(h, "//Sid")

    sid = s.text

    @message.SmsMessageSid = sid

    respond_to do |format|
      if @message.save
        flash[:notice] = 'Message was successfully created.'
        format.html { redirect_to(@message) }
        format.xml  { render :xml => @message, :status => :created, :location => @message }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @message.errors, :status => :unprocessable_entity }
      end
    end
  end

OK - this isn't very pretty. In fact, I bet there are at least 3 ways to make this more readable and maintainable. I'm using the Twilio Rest Library to format the post sending texts. The Create method is based on the standard one generated from a Rails scaffold.
