Misol
Quyidagi kod fragmenti "books.xml" faylini xmlDoc’ga yuklaydi va barcha <book> elementlariga "edition" atributini qo‘shadi:
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 x, i, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName('title');
// Add a new attribute to each title element
for (i = 0; i < x.length; i++) {
x[i].setAttribute("edition", "first");
}
// Output titles and edition value
for (i = 0; i < x.length; i++) {
txt += x[i].childNodes[0].nodeValue +
" - Edition: " +
x[i].getAttribute('edition') + "<br>";
}
document.getElementById("demo").innerHTML = txt;
}
Natija:
Everyday Italian - Edition: first
Harry Potter - Edition: first
XQuery Kick Start - Edition: first
Learning XML - Edition: first
