Mfano 1

Machache ya chaguo hii ingeza "books.xml" kwenye xmlDoc, na kutaka aina ya kiwango cha kwanza cha <title>:

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
   if (this.readyState == 4 && this.status == 200) {
       myFunction(this);
   }
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
    var xmlDoc = xml.responseXML;
    var x = xmlDoc.getElementsByTagName("title")[0];
    document.getElementById("demo").innerHTML =
    x.nodeType;
}

Tunafikia macho ya kipenzi:

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
        myFunction(this);
    }
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
// Kuangalia kuanzia cha kwanza cha kiwango kina msingi
function get_firstchild(n) {
    var x = n.firstChild;
    while (x.nodeType != 1) {
        x = x.nextSibling;
    }
    return x;
}
function myFunction(xml) {
    var x, i, txt, xmlDoc, firstNode, xmlDoc;
    xmlDoc = xml.responseXML;
    x = xmlDoc.documentElement;
    txt = "";
    firstNode = get_firstchild(x);
    for (i = 0; i < firstNode.childNodes.length; i++) { 
        if (firstNode.childNodes[i].nodeType == 1) {
            //Muungu wa kwa kufanya kipengele cha kitumiaji peke yake
            txt += firstNode.childNodes[i].nodeName + 
            " = " + 
            firstNode.childNodes[i].childNodes[0].nodeValue + "
";
        }
    }
    document.getElementById("demo").innerHTML = txt; 
}
