Get specific nested table cell using Ruby Watir

Question

I'm writing a Watir program to extract a specific number from a dynamically-generated table. The number is always in the second column of the fourth-to-last row in the table, but I'm getting the following error when trying to access the general table element:

Watir::Table: located: false; {:id=>"tContenido", :tag_name=>"table"}

Code

require 'rubygems'
require 'watir'
browser = Watir::Browser.new :firefox
$log = Logger.new('logs\test.log')
$log.info("TEST")
$log.info browser.table(:id, 'tContenido')

HTML Structure of the target page (1)

HTML Structure of the target page (2)

Any help would be greatly appreciated, thanks in advance!

Answer 1

I think this is the one you are looking for:

browser.table(id: 'tContenido').tr(class: 'tr_gris', index -1).td(index: 1).text

Alternately, if you are having problems with a table, you can just put everything into an array of Hashes:

browser.table(id: 'tContenido').hashes

Answer 2

You can write the following WATIR code

puts b.table(id: 'tContenido').trs[-4].tds[2].text
