I inherited an application from a person who was apparently taken with XML.  The app&#x27;s data and output was kept in his own home-brewed XML format with hand written output and parser functions.<p>His understanding of XML was as follows: Put whatever you want between &#x27;&lt;&#x27; &#x27;&gt;&#x27;.  It certainly beats reading the w3c docs.  Needless to say, I rewrote the application from scratch.
