<div class="textblock"><p>A <a class="el" href="classtinyxml2_1_1_x_m_l_handle.html">XMLHandle</a> is a class that wraps a node pointer with null checks; this is an incredibly useful thing. Note that <a class="el" href="classtinyxml2_1_1_x_m_l_handle.html">XMLHandle</a> is not part of the TinyXML-2 DOM structure. It is a separate utility class.</p>

<p>Take an example: </p><pre class="fragment"><Document>

A <a class="el" href="classtinyxml2_1_1_x_m_l_handle.html">XMLHandle</a> checks for null pointers so it is perfectly safe and correct to use:</p>
