title: How to select all child div with same class using Puppeteer?
body: <p>I'm new for Puppeteer and I'm trying to get textContent from two divs that using same class. </p>
  
  <pre><code>&lt;div class="post-item"&gt;
     &lt;div class="post-item-info"&gt;
        &lt;span class="post-item-status post-comment"&gt;&lt;/span&gt;
        3
     &lt;/div&gt;
     &lt;div class="post-item-info"&gt;
        &lt;span class="post-item-status post-vote"&gt;&lt;/span&gt;
        5
     &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>The result that I'm expecting is return an array [3,5]. My current code is below.</p>
  
  <pre><code>let postInfo = element.querySelector('.post-item-info');
  </code></pre>
  
  <p>The problem is it is only return the first one. Please let me know how to do it.</p>
