ruby 1.8.6

nokogiri 1.4.0

Hi. I am trying to get a number(Nikkei 225) from the web site, "Google
Finance". It's a number that indicates the average of major stock
prices, which changes in real-time.

http://www.google.com/finance?q=INDEXNIKKEI:.N225

here is the code I tried.
-------------------------------------------------
require 'rubygems'
require 'nokogiri'
require 'open-uri'

url = "http://www.google.com/finance?q=INDEXNIKKEI:.N225"

doc = Nokogiri::HTML(open(url).read)

path1 = "/html/body/div[@id='ref_15513676_l']"

p doc.xpath(path1).text()
-------------------------------------------------

but it gives nothing. But no error, though.
The full xpath for the number, which appears big and bold in the near
top of the page is

-------------------------------------------------
/html/body/div[@id='outer-wrapper']/div[@id='body-wrapper']/div[6]/div[@id='rt-content']/div/div[2]/div[2]/div[@id='market-data-div']/div[@id='price-panel']/div[1]/span/span[@id='ref_15513676_l']/span[1]
-------------------------------------------------

then I guessed that the important part would be the last one followed
from "[@id..." in comparison to the Dow average which is below.

-------------------------------------------------
/html/body/div[@id='outer-wrapper']/div[@id='body-wrapper']/div[6]/div[@id='rt-content']/div/div[2]/div[2]/div[@id='market-data-div']/div[@id='price-panel']/div[1]/span/span[@id='ref_983582_l']
-------------------------------------------------

What's wrong with my code? Could anyone help me out?

Your XPATH is wrong try

path1 = "/html/body/div//span[@id='ref_15513676_l']"
