title: Python/ Selenium: Clicking an element without id or class attribute
body: <p>I'm trying to get a program to click a button using selenium.</p>
  <p>I've tried many different <code>find_elements_by...()</code> and many different arguments, but I can't figure out which <code>find_element_by*()</code>. I need to use and what should be in the argument</p>
  <p>Where is what I'm trying to click:</p>
  <pre><code>&lt;article onclick=&quot;mainPrincipalPage.PerformCallback('Registro');&quot;&gt;
      &lt;div class=&quot;imageBox&quot;&gt;
          &lt;img src=&quot;../Images/iconRegistroHorario.svg&quot;&gt;
      &lt;/div&gt;
      &lt;div class=&quot;titleBox&quot;&gt;
          &lt;span&gt;Registro horario&lt;/span&gt;
      &lt;/div&gt;
  &lt;/article&gt;
  </code></pre>
