if (this.readyState == 4 && this.status == 200) {
myFunction(this);
}
};
xhttp.open("GET", "books_ns.xml", true);
xhttp.send();
function myFunction(xml) {
var xmlDoc = xml.responseXML;
var x = xmlDoc.getElementsByTagName("book")[0];
var ns = "https://www.w3schools.com/edition/";

Ta’rif va qo‘llanilishi
setAttributeNS() metodi yangi atribut (nomlar fazosi bilan) qo‘shadi.
Agar elementda shu nomli yoki shu nomlar fazosiga ega atribut allaqachon mavjud bo‘lsa, uning qiymati prefix va value parametrlari qiymatiga o‘zgartiriladi
Sintaksis
elementNode.setAttributeNS(ns,name,value)| Parametr | Tavsif |
|---|---|
| ns | Majburiy. O‘rnatiladigan atributning nomlar fazosi URI’sini belgilaydi |
| name | Majburiy. O‘rnatiladigan atributning nomini belgilaydi |
| value | Majburiy. O‘rnatiladigan atributning qiymatini belgilaydi |

if (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};
