XMLDOM, the System.Xml namespace and refreshing data

[BCM]

In ASP 3, I once did a page using javascript and XMLDOM that loaded up xml
files, displayed their data, and automatically refreshed that data at 10
second intervals (not a whole page refresh: just the data in the particular
node I wanted to display). The javascript looked something like:

function GetData()

{

xmldoc = new ActiveXObject("Microsoft.XMLDOM");

xmldoc.load("c:\\myxmldoc.xml");

}

function Update()

{

var myLabelText =
(xmldoc.getElementsByTagName("TimeStamp").item(0). text);

idMyLabel.innerText = myLabelText;

}

function Init()

{

GetData();

setInterval(GetData(),9000); //grab the xml doc every 9 seconds

setInterval(Update(),10000); //update the html with the data it contains
every 10 seconds

}

Then, in the HTML form, I would just call Init() during the body onLoad
event.

Surely there is a similar technique in ASP.NET using the System.XML
namespace, but after a day and a half I wave the white flag! Any
suggestions? Thanks in advance!
