I'm trying to create an AJAX image switcher for different Colored Product.

In my Page_Controller id added

if(Director::is_ajax() || $_GET["ajaxDebug"]) {
			$this->isAjax = true;
			}
			else {
				$this->isAjax = false;
				} 

Then in my ColorProduct Page Controller I added:

 function index() { 
  if($this->isAjax) {
   return $this->renderWith("ColorProductXML");
  }
  else {
   return Array();
  }  
 }

I then created a ColorProductXML tempalte and placed it in my root template directory

<?xml version="1.0" encoding="UTF-8"?>
<colorproduct>
	<% control Colors %>
	<color colorID="$StripColorName">
		<name>$ColorName</name>
		<hex>$ColorHex</hex>
		<% control ToyImageClasss %>
		<imagegroup imageName="$StripImageName">
			<type>$ImageClass</type>
			<% control ToyImages %>
				<% if Type=="Normal" %>
					<% control Attachment %>
						<thumbnail>$SetWidth(60).URL</thumbnail>
						<small>$SetWidth(460).URL</small>
						<zoom>$SetWidth(920).URL</zoom>
						<full>$URL</full>
					<% end_control %>
				<% end_if %>
				<% if Type=="Blur" %>
					<blur>$Attachment.URL</blur>
				<% end_if %>
			<% end_control %>
		</imagegroup>
		<% end_control %>
	</color>
	<% end_control %>
</colorproduct>

When I access a ColorProduct page adding ?ajax=1 to the end of my URL I get nice XML document, and my jQuery call to that url also returns a document in the same format but I can't query the nodes. Firebug shows the Content-Type as text/html instead of application/xml. How do I force SS to return an XML content type?

After a few more fruitless hours of digging I decided to copy the contents of the page with ?ajax=1 variable added and paste it into a static xml file. When my jQuery script loads THAT file i notice when I dump it i see the <?xml version="1.0" encoding="UTF-8"?> header at the top of the results but not from the "live" version

Any ideas? Enabling API access will give me an XML of the table, but I need access to resized image URLs
