title: Capybara find element by content
body: <p>Can I find an element (of any type) by its content with Capybara?</p>
  
  <p>Ideally I would like to write code like this:</p>
  
  <pre><code>find('Copy from a paragraph')    # finds the p element
  find('Copy from a link')         # finds a element
  find('Copy from a button')       # finds button element
  </code></pre>
  
  <p>etc.</p>
