XML DOM - nextSibling 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 nextSibling attribute.

The XML DOM nextSibling attribute returns the node immediately following a node (the following node in the same tree level). If no such node exists, this returns null.

Syntax

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

nodeObject.nextSibling

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 nextSibling 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>
         function get_nextsibling(n1) {
            c1 = n1.nextSibling;
            while (c1.nodeType != 1) {
               c1 = c1.nextSibling;
            }
            return c1;
         }

         xmlDoc = loadXMLDoc("/dom/node.xml");

         c1 = xmlDoc.getElementsByTagName("FirstName")[0];
         document.write(c1.nodeName);
         document.write(" and value = ");
         document.write(c1.childNodes[0].nodeValue);

         c2 = get_nextsibling(c1);

         document.write("Name of Next sibling is: ");
         document.write(c2.nodeName);
         document.write(" and value = ");
         document.write(c2.childNodes[0].nodeValue);
      </script>
   </body>
</html>

Output

Save file as nodeattribute_nextSibling.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 -

FirstName and value = Kennedy
Name of Next sibling is: LastName and value = Nkpara
