Hi,
Totally new at this, so this is the issue... I get an xml feed back from an xmlhttp query
function api_PSQT(url,string)
{
req = new ActiveXObject("Microsoft.XMLHTTP");
if (req)
{
req.onreadystatechange = processReqChange;
req.open("POST",url,true);
req.send(string);
}
}
Now I get back the xml, but how in gods name am I supposed to apply the xsl format sheet to the xml file that I received...
The only way I know how to do it, is when I have the xml file in question, I just add the header at the top of the file.. but is there a way to apply the formatting, and output it to a div's innerHTML?
Thank you in advance!

As your code is IE specific I presume that's your target browser. Given that you would create a msxml2.domdocument.3.0 using client-side code, load the XSLT and use the responseXML.transformNode method, passing in the DOM containing the stylesheet.
Look on msdn.com for msxml and transformNode.

You might want to have a look at the Sarissa Library. It does all sorts of things around XMLHTTP and XSLT for you. It's well developed and cross platform: http://sourceforge.net/projects/sarissa/

I took a look at the msdn site, and found a segment of code that I tried to implement, but it doesn't work, and I have no clue what I'm going wrong... I get the error "You have an error The filename, directory name, or volume label syntax is incorrect." I know that the xml output is fine, as I put it to a text file, changed the ext to xml, and opened it without issue.
var req;
function makeCall(url,data)
{
req = new ActiveXObject("Microsoft.XMLHTTP");
if (req)
{
req.onreadystatechange = processChange;
req.open("POST",url,true);
req.send(data);
}
}
function processChange()
{
//if request shows complete
if (req.readyState == 4)
{
// Load data.
var source = new ActiveXObject("Msxml2.DOMDocument.3.0");
source.async = false;
source.load(req.responseText);
if (source.parseError.errorCode != 0)
{
var myErr = source.parseError;
error ->>>> alert ("You have error " + myErr.reason);
}
else
{
// Load style sheet.
var stylesheet = new ActiveXObject("Msxml2.DOMDocument.3.0");
stylesheet.async = false
stylesheet.load("format.xsl");
if (stylesheet.parseError.errorCode != 0)
{
var myErr = stylesheet.parseError;
alert ("You have error " + myErr.reason);
}
else
{
// Echo back XSLT output to console
document.body.appendChild(source.transformNode(stylesheet));
}
}
}
}

That's because you're using load instead of loadXML. Either do:source.loadXML(req.responseText);
or preferably:
source.load(req.responseXML);
The latter requires that responseXML holds an XML document.
