I have the following code that reads an XML, makes changes, opens a window, and writes the XML into the document. The problem is that the content is not rendered as XML. Any way to set a content type, etc, to have the browser handle the content as XML?

<script>
var wxml;
var xDoc;
var xDevices, xInputs;
var xDevice, xInput;

    function fSetXmlAInput(iDevice, iNode, nodeNewVal) {
      xInput = xInputs[iNode];
      xValue = xInput.getElementsByTagName("value")[0];

      // change node value:
      // console.log("nodeVal: " + xValue.firstChild.nodeValue);
      xValue.firstChild.nodeValue = nodeNewVal;
      // console.log("newVal: " + xValue.firstChild.nodeValue);
    }

    function fSetXmlDevice(iDevice) {
      xDevice = xDevices[iDevice];
      xInputs = xDevice.getElementsByTagName("input");
        fSetXmlAInput(iDevice, 0, "22");
        fSetXmlAInput(iDevice, 1, "33");
    }

    function alternativeLoadXML3() {
        // load xml file
        if (window.XMLHttpRequest) {
            xhttp = new XMLHttpRequest();
        } else { // IE 5/6
            xhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }

        xhttp.open("GET", "my_template.xml", false);
        xhttp.send();

        xDoc = xhttp.responseXML;
        xDevices = xDoc.getElementsByTagName("device");
        fSetXmlDevice(1);

        var xmlText = serializeXmlNode(xDoc);

        var newWindow = window.open("my_template.xml", "Test", "width=300,height=300,scrollbars=1,resizable=1");
        newWindow.document.open();
        newWindow.document.write(xmlText);
        newWindow.document.close()
    };

</script>

Below the XML as well:

<?xml version="1.0" encoding="utf-8"?>
<myXmlRoot>
<device>
  <input><name>"name 1"</name><value>{replaceMe!}</value></input>
  <input><name>"name 2"</name><value>{replaceMe!}</value></input>  
</device>
<device>
  <input><name>"name 1"</name><value>{replaceMe!}</value></input>
  <input><name>"name 2"</name><value>{replaceMe!}</value></input>  
</device>
<device>
  <input><name>"name 1"</name><value>{replaceMe!}</value></input>
  <input><name>"name 2"</name><value>{replaceMe!}</value></input>  
</device>
</myXmlRoot>

Any way to force the browser to render content in new window as XML...or does using document.open and document.write mean code is rendered as HTML?

Use dataURI to write xml into new window is very easy.

window.open('data:text/xml,'+encodeURIComponent(xmlText),
     "Test", "width=300,height=300,scrollbars=1,resizable=1");

Both document.open and document.write are used to write HTML or Javascript to a document. This goes back to the DOM Level 2 Specification of document.open, which assumes that the document is opened in order to write unparsed HTML.

Instead of using document.open and document.write, I would instead suggest dymanically adding elements using the XML DOM as in sampleElement.appendChild(XMLnode)
