require 'HTTParty'

require 'nokogiri'

### Obtain stock symbol:
puts "Please enter your Stock Symbol:"
stock_symbol = gets.chomp

address = "http://finance.yahoo.com/q?s=" + stock_symbol 
# puts address

### run a GET from Yahoo with HTTParty for your stock symbol, assign to response
response = HTTParty.get("#{address}")

### take response body and use Nokogiri to parse the HTML into a Ruby variable
ticker = Nokogiri::HTML(response.body)
span = "//span[@id='yfs_l84_" + stock_symbol.downcase + "\']"
# puts span

### 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}").first.content

value = ticker.xpath("#{span}").first.content

# p ticker
puts stock_symbol + "\'s Stock value is: $#{value}"
