summary node of mydvd7.xml is very shallow, as it does not have any grandchildren. It has five child nodes:
heading (xmlDoc.childNodes[3].childNodes[0].childNodes[0].nodeName)subhead (xmlDoc.childNodes[3].childNodes[0].childNodes[1].nodeName)description (xmlDoc.childNodes[3].childNodes[0].childNodes[2].nodeName)author (xmlDoc.childNodes[3].childNodes[0].childNodes[3].nodeName)date (xmlDoc.childNodes[3].childNodes[0].childNodes[4].nodeName)
mydvd7.xml for your reference:
<?xml version="1.0"?>
