title: loop through divs inside a div
body: <p>I need an idea on how to start a loop where I can get the innerHTML for the 3 divs inside a div:</p>
  
  <pre><code>&lt;div id="hi"&gt;
   &lt;div&gt; Item1 &lt;/div&gt;
   &lt;div&gt; Item2 &lt;/div&gt;
   &lt;div&gt; Item3 &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I need to make a function that search through the item list and see for common items. I know one way is to use <code>document.getElementsByTagName</code> but I don't need to see the innerHTML for each div.</p>
