title: Typoscript | How to write this like an IF ELSE condition?
body: <p>I'm new to Typo3, and building a site with TemplaVoila.
  I got the following TS (within TV XML) which outputs 2 sets of content</p>
  
  <pre><code>10= RECORDS
  10.source.current=1
  10.tables = tt_content
  10.wrap.required = 1
  10.wrap = &lt;!--TYPO3SEARCH_begin--&gt; | &lt;!--TYPO3SEARCH_end--&gt;]]&gt;
  
  20 = CONTENT
  20.table = tt_content
  20.select {
    pidInList = 36
  }
  </code></pre>
  
  <p>The first set (10) is the current page content, and the second (20) fetches content from page ID 36.
  Currently both are printed, but I want 20 to print only if 10 is empty.</p>
  
  <p>How can I achieve this?</p>
