XML DOM prefix Property
Node Object
Example
The following code fragment loads "books_ns.xml" into xmlDoc and returns the namespace prefix of the <title> elements:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};
xhttp.open("GET", "books_ns.xml", true);
xhttp.send();
function myFunction(xml) {
var x, i, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName("title");
for (i = 0; i < x.length; i++) {
txt += "Prefix: " + x.item(i).prefix + "<br>";
}
document.getElementById("demo").innerHTML = txt;
}
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};
xhttp.open("GET", "books_ns.xml", true);
xhttp.send();
function myFunction(xml) {
var x, i, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName("title");
for (i = 0; i < x.length; i++) {
