Wondering if anyone can help me include a loop into my xml using dom. Whenever I try to launch this page the system crashes.
<html>
<head>
<title>BQI DOM Example</title>
<script language="JavaScript">
function getActiveClasses()
{
xmlDocumentObject = new ActiveXObject ("Microsoft.XMLDOM")
xmlDocumentObject.load("bqiclasses.xml")
var bqiclassesNode, classNode, courseNode, statusNode, displayText
bqiclassesNode = xmlDocumentObject.documentElement
classNode = bqiclassesNode.firstChild
courseNode = classNode.firstChild.nextSibling.nextSibling.text
statusNode = classNode.lastChild.text
for (var i = 0; statusNode = '1'; i++)
{
displayText = "Active Classes: " + courseNode + " - " + "Status: " + statusNode
displayDIV.innerHTML = displayText
}
}
</script>
</head>
<body>
<input type="button" value="Display Active Classes" onclick="getActiveClasses()">
<br />
<div id="displayDIV"/>
</input>
</body>
</html>

You have an infinite loop there. Instead, use this construct:
for(var i = 0; i < theNode.childNodes.length; ++i) {
currentChild = theNode.childNodes[i];
}

And also...
"Microsoft.XmlDom" is severely deprecated as you don't know what dom class you'll get. If you can control the environment you use install version 4.0 sp2 from msdn and use "Msxml2.DomDocument.4.0" or failing that most machines will have version 3, "Msxml2.DomDocument.3.0".
If you use "Microsoft.XmlDom" you could get the pre XPath parser, it only supports XSLPattern which has a different syntax entirely for searches.

Thanks Armen, Thanks Joe! I am new to xml and only a novice with JavaScript so I appreciate your tips. I kept thinking about this all night and I wondered if I had an infinite loop. Again, thank you VERY MUCH!
