Active Calendar Class :: Example Code

<?php
/*
********************************************************************************
This example script demontrates how you could create event dates with linkable contents
in the Active Calendar, using records from an xml file.
The event file is included in this package as 'xmlevents.xml':
Please make sure that this script has the rights to read it.
Keep in mind that this script does not use any real xml parser (you may not have one).
It just 'parses' the xml file as it is. So do not change its basic structure.
The element names can be changed though and of course more events and contents can be added!
If you have an xml parser just modify this script according to its methods...
