Cannot run the example code. #55

Hi, I got wombat.rb:14:in block (3 levels) in <main>': undefined method gsub' for nil:NilClass (NoMethodError) error when running the example code at the introduction page of wombat.

I guess the reason for this error is that github has changed its home page's code. This makes the variable e become nil.

Anyone knows how to fix this problem? I'm not familiar with xpath. I just started learning xpath.

yeah that's definitely it. I wrote that example a long time ago and the github page is no longer the same. I'll update the examples to reflect the current page.
