Misol
Quyidagi kod fragmenti "books.xml" faylini xmlDoc’ga yuklaydi va har bir <book> elementiga nomlar fazosiga ega element tugunini 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, y, z, i, newel, newtext, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName("book");
for (i = 0; i < x.length; i++) {
newel = xmlDoc.createElementNS("p", "edition");
newtext = xmlDoc.createTextNode("First");
newel.appendChild(newtext);
x[i].appendChild(newel);
}
// Output all titles and editions
y = xmlDoc.getElementsByTagName("title");
z = xmlDoc.getElementsByTagNameNS("p","edition");
for (i = 0; i < y.length; i++) {
txt += y[i].childNodes[0].nodeValue +
" - " +
z[i].childNodes[0].nodeValue +
" edition." +
" Namespace: " +
z[i].namespaceURI + "<br>";
}
document.getElementById("demo").innerHTML = txt;
}
Yuqoridagi kodning natijasi quyidagicha bo‘ladi:
Everyday Italian - First edition. Namespace: p
Harry Potter - First edition. Namespace: p
XQuery Kick Start - First edition. Namespace: p
Learning XML - First edition. Namespace: p
