var url = "http://localhost:8080/siteuser/webresources/site.users/";
var xmlhttp = new XMLHttpRequest();

myFunction(this);
}

xmlhttp.open("GET", url, true);
xmlhttp.send();

var xmlDoc = xml.responseXML;
var table="<tr><th></th>Email<th>ID</th><th>Password</th><th>User Type</th><th>User Name</th></tr>";
var x = xmlDoc.getElementsByTagName("users");
for (i = 0; i <x.length; i++) {
table += "<tr><td>" +
x[i].getElementsByTagName("email")[0].childNodes[0].nodeValue +
