title: Selenium Python: How to click on a <a> tag based on "onclick" text
body: <p>So this page has several</p>
  
  <pre><code>&lt;a href="#" onclick="showpage('potato.php');"&gt;...
  &lt;a href="#" onclick="showpage('carrots.php');"&gt;...
  &lt;a href="#" onclick="showpage('chicken.php');"&gt;...
  &lt;a href="#" onclick="showpage('fish.php');"&gt;...
  </code></pre>
  
  <p>of these tags. While I could do a find_elements_by_xpath and then pick the one I want, is there a way to say in specific, I want to click on the potato link?</p>
