title: liferay velocity get first children or first sibling
body: <p>Is there a way instead of getting all the children or all the siblings with $var.getChildren() and $var.getSiblings() to get only the first child or the first sibling ?</p>
  
  <p>I couldn't find anything else besides looping through the elements.</p>
  
  <p>Does $var.getChildren(1) work?</p>
