Quiz

The attribute namespaceURI specifies the namespace URI of a node.

Syntax

Following is the syntax for the usage of the namespaceURI attribute.

nodeObject.namespaceURI

Example

node_ns.xml contents are as below −

<?xml version = "1.0"?>
<Company>
   <Employee Employee xmlns:e = "http://www.tutorials.com/technical/" category = "technical">
      <e:FirstName>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>Taniya</n:FirstName>
      <n:LastName>Mishra</n:LastName>
      <n:ContactNo>1234667898</n:ContactNo>
      <n:Email>taniyamishra@xyz.com</n:Email>
   </Employee>
</Company>

Following example demonstrates the usage of the namespaceURI attribute −

<!DOCTYPE html>
   <html>
      <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>
      <body>
         <script>
            xmlDoc = loadXMLDoc("/dom/node_ns.xml");

            x = xmlDoc.getElementsByTagName('Employee');

            document.write("Namespace URI of attribute node is: ");
            document.write(x.item(0).attributes[0].namespaceURI);
         </script>
    </body>
</html>

Execution

Save this file as nodeattribute_namespaceuri.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 −

Namespace URI of attribute node is: http://www.w3.org/2000/xmlns/
