title: getElementsByFieldName ? Get all elements of a radioenum that have a certain field name
body: <p>I have a radioenum html that looks like</p>
  
  <pre><code>&lt;div class="col-xs-12" type="radioenum" field="arr_c"&gt;
  // elements
  &lt;/div&gt;
  </code></pre>
  
  <p>I'm trying to get the elements it contains, but not sure how to proceed</p>
  
  <p>There's no function called getElementsByFieldName that can be called and class name is not unique so I can't use getElementsByClassName</p>
