XML DOM - childNodes 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 childNodes attribute.

The childNodes attribute describes the child node from the NodeList for a node.

Syntax

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

nodeObject.childNodes

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 childNodes attribute -

<!DOCTYPE html>
<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.childNodes;
         for (i = 0;i < x.length;i ++) {
            document.write("Nodename: " + x[i].nodeName);
            document.write(" (nodetype: " + x[i].nodeType + ")<br>");
         }
      </script>
   </body>
</html>

Output

Save file as nodeattribute_childnodes.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 -

Nodename: Company (nodetype:  1)
