title: Xpath to parse the background image url from a style tag
body: <pre><code>&lt;div class="card-image" style="background-image: url("https://cdn6.bigcommerce.com/s-0kvv9/images/stencil/500x659/products/170691/242554/dicemastgreenflash__36803.1503934716.jpg?c=2");"&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>When I input this,</p>
  
  <pre><code>.//*[@class='card-image']/@style
  </code></pre>
  
  <p>it returns this:</p>
  
  <pre><code>background-image:url('https://cdn6.bigcommerce.com/s-0kvv9/images/stencil/500x659/products/170691/242554/dicemastgreenflash__36803.1503934716.jpg?c=2');
  </code></pre>
  
  <p>I only want it to return the URL.</p>
