title: XML item is the same as php key word
body: <p>I have xml item</p>
  
  <pre><code>&lt;parent&gt;0&lt;/parent&gt;
  </code></pre>
  
  <p>in my xml file. I need to add it to the variable in PHP such as</p>
  
  <pre><code>$parent = htmlspecialchars($fce_pridej_polozka_kategorie_xml-&gt;parent);
  </code></pre>
  
  <p>But parent is the keyword of PHP so the command is not functional.</p>
  
  <p>What to do with this?</p>
