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

Example
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
