title: vQmod code syntax
body: <p>I'm writing vqmod opencart modification and got one problem. There's a basic code:</p>
  
  <pre><code>&lt;operation&gt;
  &lt;search position="after"&gt;&lt;![CDATA[&lt;?php echo $description; ?&gt;&lt;/div&gt;&lt;/div&gt;]]&gt;&lt;/search&gt;
  &lt;add&gt;
  &lt;![CDATA[&lt;div class="content"&gt;&lt;h2&gt;Testimonials&lt;/h2&gt;&lt;div class="box-testimonial"&gt;&lt;?php echo $description_new; ?&gt;&lt;/div&gt;&lt;/div&gt;]]&gt;
  &lt;/add&gt;
  &lt;/operation&gt;
  </code></pre>
  
  <p>So What I want to do is to make some kind of conditional to display the code from  only when $description_new is not empty. What will be the syntax in this vqmode code?</p>
  
  <p>Thanks in advance,
  Arek</p>
