No it is white spoace _text_ nodes that are stripped. element nodes are
not text nodes.

in 
<x>
  <a>
    <b> </b>
    <c> 123 </c>
   </a>
</x>

there are 6 white space text nodes, using * to mark white space
characters they are:

<x>***<a>*****<b>*</b>*****<c> 123 </c>****</a>*</x>

testing for empty is a FAQ on this list as the archives will show.

You test us equaivlent to

//myel[string(.)]
other tests are
//myel[*]  (has element children)
//myel[normalize-space(.)] (has non white space text)
//myel[node()] has children (including comments and white space text node)
