Hello folks! welcome back to a new edition of our tutorial on XML DOM. In this tutorial guide, we will be discussing about the XML DOM Element Object setAttribute Method.

The XML DOM Element Object setAttribute method is used to set a new attribute value to the existing element.

elementObj.setAttribute(name)

Parameter Details

S.No.Parameter & Description

It holds the name of the attribute to retrieve.


Return Value

Following are the node.xml contents -

<?xml version = "1.0"?>
<Company>
   <Employee category = "Technical">
      <FirstName>Kennedy</FirstName>
      <LastName>Nkpara</LastName>
      <ContactNo>1234567890</ContactNo>
      <Email>kennedynkpara@xyz.com</Email>
   </Employee>
   
   <Employee category = "Non-Technical">
      <FirstName>Justice</FirstName>
      <LastName>Douglas</LastName>
      <ContactNo>1234667898</ContactNo>
      <Email>justicedauglas@xyz.com</Email>
   </Employee>
   
   <Employee category = "Management">
      <FirstName>Stephanie</FirstName>
      <LastName>Francis</LastName>
      <ContactNo>1234562350</ContactNo>
      <Email>stephaniefrancis@xyz.com</Email>
   </Employee>
</Company>


The following example illustrates the usage of the Element Object setAttribute method -

<!DOCTYPE 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.xml");

         x = xmlDoc.getElementsByTagName('Employee');
         for(i = 0;i < x.length;i++) {
            x.item(i).setAttribute("category","HR");
         }

         document.write("Values of all attribute after using setattribute method: ");
         for (i = 0;i < x.length;i++) {
            
            document.write(x[i].getAttribute('category'));
            document.write("<br>");
         }
      </script>
   </body>
</html>

Output

Save this file as elementmethod_setattribute.html on the server's path (this file and node.xml should be on the same path in your server). This is going to give us the following output below -

Values of all attribute after using setattribute method: 
HR
HR
HR
