title: Puppeteer: Find element by HTML attribute
body: <p>Essentially, I am trying to get Puppeteer to find an element on this page by its attribute <strong>data-form-field-value</strong> which must equal <strong>244103310504090</strong>.</p>
  
  <p>This is the HTML code to the button:</p>
  
  <pre><code>&lt;section class="fl-accordion-tab--content"&gt;
  &lt;div class="fl-product-size"&gt;
  &lt;/button&gt;&lt;button class="fl-product-size--item fl-product-size--item__is- 
  selected" type="button" data-form-field-target="SKU" data-form-field-base-css- 
  name="fl-product-size--item" data-form-field-value="244103310504090" data-form- 
  field-unselect-group="" data-testid="fl-size-244103310504-US-9" data-product- 
  size-select-item="244103310504090" data-form-field-selected="true"&gt;
  &lt;span&gt;9&lt;/span&gt;
  &lt;/button&gt;&lt;/div&gt;
  &lt;/section&gt;
  </code></pre>
  
  <p>I've tried with a few things however I cannot seem to find a solution, any help is appreciated!</p>
