title: How to assert on number of html table rows in ruby using capybara + cucumber
body: <p>I am trying to get to grips with BDD web development in Ruby using cucumber + capybara and I am stuck at what should be an easy task - just to check the number of rows in a table. The intention of what I'm trying to achieve is something along the lines of:</p>
  
  <pre><code>page.should have_xpath("//table[@id='myTable']")
  find("//table[@id='myTable']/tr").length.should == 3
  </code></pre>
  
  <p>But this doesn't work (missing method length) and I can't find a way to assert against the table length.</p>
  
  <p>Any ideas anyone (please be easy on me tho' I'm a ruby nooby)</p>
  
  <p>Thanks in advance</p>
  
  <p>Neil</p>
