I'm just beginning to get into the XSLT thing and have been studying several 
samples from different sites. I'm particularly impressed with the seven part 
series by Joe Slovinski at http://www.15seconds.com/issue/010921.htm. I've 
down loaded the samples and have them on the desktop for play time (Win XP, 
SP2, IE6.0). Other than an "access denied" message, things are pretty much 
as advertised. I can not for the life of me figure out what permissions need 
to granted or where to set them in order for the example to save a copy of 
the local XML back to the local system.

Here's two of the JavaScript functions involved. Other than my "save" 
problem, I've been able to walk through the series ( with a half dozen or so 
new books) and understand what's going on...

Any help would be greatly appriciated.

function updateEntity(entityID) {
var entity;
var xslDoc;
var container;
var i;
xslDoc = new ActiveXObject('MSXML2.FreeThreadedDOMDocument')
xslDoc.async = false;
xslDoc.load("admin/tree.xslt");
entity = xmlDoc.documentElement.selectSingleNode("//entity[@id='" + entityID 
+"']");
for(i=0; i < entity.childNodes.length; i++) {
if(entity.childNodes(i).baseName != "contents") {
entity.childNodes(i).text = 
document.all[entity.childNodes(i).baseName].value;
}
}
container = document.createElement("DIV");
container.innerHTML = entity.transformNode(xslDoc)
container.childNodes(0).style.display = "block";
document.all[entityID].swapNode(container.childNodes(0));
container = null;
saveXML();
}
function saveXML() {
try {
xmlDoc.save(xmlDoc.XMLDocument);
}
catch (e) {
displayError("Error updating XML feed: " + e.message + ". Please check your 
local directory and file permissions.", 8000)
}
}
