Stock Ticker

stock_ticker.rb

require 'HTTParty'
require 'json'
require 'nokogiri'

### run a GET from Yahoo with HTTParty for Apple Stock, assign to response
response = HTTParty.get('http://finance.yahoo.com/q?s=AAPL')

### take response body and use Nokogiri to parse the HTML into a Ruby variable
ticker = Nokogiri::HTML(response.body)

### use the xpath method to isolate the stock value from the parsed HTML
### use the .first method to get the first element of the NodeSet

puts ticker.xpath("//span[@id='yfs_l84_aapl']").first

### The output of the above "contains" my desired value.
### Use the .content method to get the value only:

puts ticker.xpath("//span[@id='yfs_l84_aapl']").first.content
