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 <user>text data</user>, 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);
}
