Watir: How do i get inner_html of multiple span, with same class name

I am using this code, to grab the inner_html of the span class.

weather = browser.span(:class => "_Xbe kno-fv").inner_html
puts weather

However, Multiple inner_html exists with the same class, in the page. How do I retrieve all of them at once?

I am trying to get the information relating to weather from this page

weather = browser.span(:class => "_Xbe kno-fv").text
puts weather

This above code, prints, the text but not consistently. I beleive, since multiple elements exists with the same class or the information is dynamic and hence? I am not sure. Is there a way to get this? 4

Solution

The element that you are targeting is contained within a <div> with a unique data attribute. I'd advise using that approach:

require 'watir'    
b = Watir::Browser.new :chrome
b.goto "https://www.google.com/?gfe_rd=cr&ei=w7-YWN75OsyAoAPK_oDYBQ#q=bangalore" 

puts b.div(:data_attrid => "kc:/location/citytown:current weather").text
#=> Weather: 59°F (15°C), Wind S at 2 mph (3 km/h), 83% Humidity

For reference--as @JustinKo demonstrates--watir can use data attributes as locators with some minor tweaks.
