AJAX在ASPX页面中输出XML

Question

I have this ajax in my login page, and I reference a checker.aspx that checks if the username and password is valid and returns 0 or 1. How do I return 0 or 1 in xml in my checker page ? Is it possible with AJAX ?

function getResult() {

    var xmlhttp = new XMLHttpRequest();
    xmlhttp.onreadystatechange = function () {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
            document.getElementById("lblMessage").innerHTML = xmlhttp.responseText;
        }
    }
    xmlhttp.open("GET", "checker.aspx?username=" + document.getElementById("txtUserName").value + "&password=" + document.getElementById("txtPassword").value, true);
            xmlhttp.send();

}

You could use return this.Content(xmlString, "text/xml"); to return a built XML string from an action.
