RegEx would be better but this works:
<html>
<head>
<title>Total.htm</title>
<script type="text/javascript">
function total() {
var sURL = "http://www.2beyourself.com/t/sample.html";
var oXML = new ActiveXObject("Microsoft.XMLHTTP");
oXML.Open("GET",sURL,false);
oXML.send();
try {
var sXML = oXML.ResponseText;
// Find Total's label
var iTAG = sXML.indexOf("<b>Total:</b>");
var sVAL = sXML.substr(iTAG);
// Find Total's decimal
var iDOT = sVAL.indexOf(".");
sVAL = sVAL.substr(0,iDOT+3);
// Find Total's start
iTAG = sVAL.lastIndexOf(">")
sVAL = sVAL.substr(iTAG+1)
// Show Total's value
alert(sVAL);
} catch(e) {
alert(sURL + " not found!");
}
}
</script>
</head>
<body onload="total()">
</body>
</html>
