XML Node error

[anom217]

I'm trying to create an InstallScript function that will parse through a XML file and retrieve the value of an attribute. But whenever I try to create a node, it fails.

set oDoc = CreateObject("Microsoft.XMLDOM");
	if(IsObject(oDoc) = FALSE) then
		MessageBox("MSXML DOM-Document Connection Failed" , 0);
		return -1;
	endif;	
	oDoc.async = FALSE;
	oDoc.setProperty("SelectionLanguage", "XPath");
	oDoc.load(svFile);
try
        set oNodeList = oDoc.getElementsByTagName("*");
catch
        MessageBox("Error creating node list", SEVERE);
	return -1;
endcatch;
	
if(oNodeList.length = 0) then
    	MessageBox("No matching elements found", 0);
    	return -1;
endif;

for ii = 0 to (oNodeList.length - 1);
        try
    		set oNode = oNodeList.nextNode;
    	catch
    		MessageBox("Couldn't assign node", SEVERE);
    	endcatch;
    	try
    	svAttributeValue = oNode.attributes.getNamedItem(svAttribute).value;
    	catch                                                            
    		svAttributeValue = "";
    	endcatch;
endfor;

There is an exception thrown when

set oNode = oNodeList.nextNode;

is called. The nodeList has several nodes, I've printed out their names to be sure. But for some reason, it won't create the node object itself!

This is the content of my sample xml file.





Anyone have any idea why the node object fails to create?

I'm still having this issue...and I can't seem to figure out what's going wrong. Anyone else had a similar problem?
