title: 'getElement(s)By' in the PHP class SimpleXML like in PHP-DomDocument?
body: <p>I have made a application using DomDocument &amp; SimpleXML, but the server doesn't support DomDocument (Only SimpleXML). Now I am rewriting it, but there aren't any functions in SimpleXML like "getElementsByTagName" and "getElementById" (I only need those 2). I have searched a lot on php.net &amp; google.com, but can't find one.</p>
  
  <p>I am not that good to write my own. So, does anyone know a alternative/function/tip/script for me? :)</p>
  
  <p>Thanks in advance.</p>
