title: capybara: find(element) using selector to target a complex attribute name
body: <p>Using cucumber and capybara to test a rails app. Assuming I cannot change the markup, can I use capybara to select the following select in a page full of similar <code>td</code>s and <code>select</code>s?</p>
  
  <pre><code>&lt;td&gt;
    &lt;select name="attributes[ruby][category]"&gt;
      &lt;option value="2" selected="selected"&gt;Languages&lt;/option&gt;
      &lt;option value="3"&gt;Communication&lt;/option&gt;
    &lt;/select&gt;
  &lt;/td&gt;
  </code></pre>
  
  <p>This seems to fail (I assume because of the nested "[" and "]").</p>
  
  <pre><code>find("select[name=attributes[ruby][category]]")
  </code></pre>
  
  <p>Escaping doesn't work either. Thoughts?</p>
