<p>What was the result of testing it? Not working?</p>
<p>The <code>while()</code> is there to deal with xml docs that have many <code>dialog</code> nodes. The <code>do { ... } while ()</code> is to find the next node with <code>dialog</code> name. These are to be compliant with xml specs, as there can be other nodes with different names. So just doing <code>node=node->next</code> doesn't ensure it will be the next <code>dialog</code> node, but the next node in the xml document.</p>
