| S.No. | Parameter & Description |
|---|---|
| 1 | namespace Is a string specifying the namespace of the attribute. |
| 2 | nodeName Is a string specifying the name of the attribute. |

Example
node_ns.xml contents are as below −
<?xml version = "1.0"?>
<Company>
<Employee xmlns:e = "http://www.tutorials.com/technical/" category = "technical">
<e:FirstName e:lang = "en">Tanmay</e:FirstName>
<e:LastName>Patil</e:LastName>
<e:ContactNo>1234567890</e:ContactNo>
<e:Email>tanmaypatil@xyz.com</e:Email>
</Employee>
<Employee xmlns:n = "http://www.tutorials.com/non-technical/" category = "non-technical">
<n:FirstName n:lang = "en">Taniya</n:FirstName>
<n:LastName>Mishra</n:LastName>
<n:ContactNo>1234667898</n:ContactNo>
<n:Email>taniyamishra@xyz.com</n:Email>

Following example demonstrates the usage of the getAttributeNodeNS method −
<!DOCTYPE html>
<html>
<head>
<script>
function loadXMLDoc(filename) {
if (window.XMLHttpRequest) {
xhttp = new XMLHttpRequest();
} else // code for IE5 and IE6 {
xhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.open("GET",filename,false);
xhttp.send();
return xhttp.responseXML;
}
</script>
</head>
<body>
<script>
xmlDoc = loadXMLDoc("/dom/node_ns.xml");
x = xmlDoc.getElementsByTagName("FirstName")[0];
ns="http://www.tutorials.com/technical/";
var attributenodens = x.getAttributeNodeNS(ns,"lang")
document.write("nodename: "+attributenodens.nodeName);
document.write("<br>nodevalue: "+attributenodens.nodeValue);
</script>
</body>
</html>
Execution
Save this file as elementattribute_getAttributeNodeNS.htm on the server path (this file and node_ns.xml should be on the same path in your server). We will get the output as shown below −
nodename: e:lang nodevalue: en
dom_element_object.htm
