XML DOM specified Property
Attr Object
Example
The following code fragment loads "books.xml" into xmlDoc and displays the name and value of the category attribute:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
��� if (xhttp.readyState == 4 && xhttp.status == 200) {
������� myFunction(xhttp);
��� }
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
var x, i, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = ""
x = xmlDoc.getElementsByTagName('book');
for (i = 0; i
< x.length; i++) {
txt +=
x.item(i).attributes[0].specified + "<br>";
}
document.getElementById("demo").innerHTML = txt;
}
