Misol
Quyidagi kod fragmenti "books.xml" faylini xmlDoc’ga yuklaydi va birinchi <book> elementidagi atributlar sonini oladi:
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("book");
document.getElementById("demo").innerHTML =
"Number of attributes in the first book element: " +
x.item(0).attributes.length;
}
Yuqoridagi kodning natijasi quyidagicha bo‘ladi:
Number of attributes in the first book element: 1
