One of the least intuitive things about parsing XML is that the text inside the element tags is actually a node you have to traverse into.

Assuming it's text data, you not only have to traverse into the text node of the user element to extract your text data, but you have to create a text node with that data in the DOM to see it. See nodeValue and and createtextnode:

// get XML 
var xml = xhr.responseXML;

// get users
var users = xml.getElementsByTagName("user");
for (var i = 0; i < users.length; i++) {   
    var user = users[i].firstChild.nodeValue;
    var tr = document.createElement("tr");
    var td = document.createElement("td");
    var textNode = document.createTextNode(user);
    td.appendChild(textNode);        
    tr.appendChild(td);        
    document.getElementById("tbody").appendChild(tr);
}
