XML DOM - lastChild Attribute


Hello folks! welcome back to a new edition of our tutorial on XML DOM. In this tutorial, we are going to be studying about the XML DOM lastChild attribute.

The XML DOM lastChild attribute specifies the last child of a node.

Syntax

The following below is the syntax to use the lastChild attribute -

nodeObject.lastChild

Example

Following below 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>Stephanie</FirstName>
      <LastName>Francis</LastName>
      <ContactNo>1234667898</ContactNo>
      <Email>stephaniefrancis@xyz.com</Email>
   </Employee>
   
   <Employee category = "Management">
      <FirstName>Justice</FirstName>
      <LastName>Dauglas</LastName>
      <ContactNo>1234562350</ContactNo>
      <Email>justicedauglas@xyz.com</Email>
   </Employee>
</Company>


The following example below illustrates the usage of the lastChild attribute -

<!DOCTYPE html>
<html>
   <body>
      <script>
         if (window.XMLHttpRequest) {
            xmlhttp = new XMLHttpRequest();
         } else {
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
         }
         xmlhttp.open("GET","/dom/node.xml",false);
         xmlhttp.send();
         xmlDoc = xmlhttp.responseXML;

         function get_lastChild(p) {
            a = p.lastChild;
            while (a.nodeType != 1) {
               a = a.previousSibling;
            }
            return a;
         }

         x = get_lastChild(xmlDoc.getElementsByTagName("Employee")[0]);
         document.write("Last child is : ");
         document.write(x.nodeName);
      </script>
   </body>
</html>

Output

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

Last child is : Email
