title: Display Product Attribute Value only if it exists
body: <p>Surprisingly can't find anything on this... basically I call my custom product attributes on the product view page like this:</p>
  
  <pre><code>Men / Women: &lt;?php echo $this-&gt;htmlEscape($_product-&gt;getmenwomen()) ?&gt;
  </code></pre>
  
  <p>This displays the men/women attribute fine, but these are optional values, so if a product doesn't have a value for this particular attribute, the line is still displayed, just with no value:</p>
  
  <pre><code>Men / Women:
  </code></pre>
  
  <p>I'd like that line to not show at all if there is indeed, no value for a product. Any ideas?</p>
