Hi folks,
Please welcome the newest user of watir! I just heard about watir when
searching for web automation, and after reading some how-to articles, I
was quite excited with my first script running below (run fine in ubuntu
x86, havent tried in mac or windows yet):
#### CODE START ####
#!/usr/bin/env ruby
require 'rubygems'
require 'watir'
require 'nokogiri'
#require 'watir-webdriver'
#start the browser up
#browser = Watir::Browser.new :chorme
browser = Watir::Browser.start
"https://www.google.com/accounts/ServiceLogin?service=mail";
#pass in current page's html to nokogiri for parsing
page_html = Nokogiri::HTML.parse(browser.html)
text = page_html.xpath(".//*[@id='quota']").inner_text
while((text.to_f)<7621.000000)
page_html = Nokogiri::HTML.parse(browser.html)
text = page_html.xpath(".//*[@id='quota']").inner_text
puts text
sleep 2
end
#### CODE END ####
Since I am totally new to watir, I would appreciate any one helping me
with my questions below:
* Main advantage of watir compared to traditional method (manual
crawling), as far as I understand, is to reduce the number of automated
queries sent to the interested page. With what I am doing above, am I
doing it right? Is it considered as one query each time when I call
page_html.xpath(".//*[@id='quota']").inner_text? If not, then anyone can
explain to me how it is working?
* I have the feeling that the code above works as to extract infos
from HTML code, whereas the quote produced from gmail is from a
javascript. Is there a way that I capture infos from javascript instead
of HTML code?
* Now if I want to *detect* the change of quota, meaning I want a kind
of *real-time* code that reports me quota anytime when quote on gmail
changes its value. Anyone can recommend me how to achieve that?
Thanks so much in advances, and sorry for many questions.
D.
