How can I parse a remote website with JavaScript?

I have a heavily locked down machines on a LAN (no internet access).

I need to create some form of application that will parse a remote web page for a certain word, and display a message if it is found.

Due to the restrictions on the machine (I can't run any applications, I can't run any vbs files, etc), I believe the best option is JavaScript running through Internet Explorer 6, but I am open to other ideas.

For a real example that can be tested, I would like to be notified if http://www.google.ca contains the word "Web" (it does).

My main issue seems to be with the same origin policy, but I don't know if there's a way around that, since I only want to read the remote site, and not interact with it.

can you run HTA ?

<html>
<head>
<script>
function showData() {
  var html = if1.document.getElementsByTagName('html')[0].innerHTML
  document.getElementById('t1').value=html
  var webPos = html.toLowerCase().indexOf('web');
  if (webPos!=-1) alert('web found :' +html.substring(webPos-10,webPos+10))
 
}
</script>
</head>
<body>
<textarea id="t1" style="width:100%; height:5%"></textarea><br />
<iframe name="if1" style="width:100%; height:95%" src="http://www.google.ca" application="yes" onLoad="showData(this)"></iframe>
</body>
</html>

Open in new window

The problem is that there's no internet connection, so it needs to be running within the LAN.
