Example
Following are the node.xml contents -

The following example illustrates the usage of the Element Object removeAttributeNode 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++) { while (x[i].attributes.length > 0) { y = x[i].attributes[0]; z = x[i].removeAttributeNode(y); document.write("Removed : " + z.nodeName) document.write(": " + z.nodeValue) document.write("<br>") } } </script> </body> </html>
Output
Save this file as elementmethod_removeattributenode.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 -
Removed : category: technical Removed : category: non-technical Removed : category: Management
