XML DOM - nodeValue 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 nodeValue attribute.

The XML DOM nodeValue is used to specify the value of a node depending on their type.

Syntax

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

nodeObject.nodeValue

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 nodeValue attribute -

<!DOCTYPE html>
<html>
   <body>
      <div>
         <b>FirstName:</b><span id = "FirstName"></span><br>
         <b>LastName:</b> <span id = "LastName"></span><br>

      </div>
      <script>
         if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
         } else {// code for IE6, IE5
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
         }
         xmlhttp.open("GET","/dom/node.xml",false);
         xmlhttp.send();
         xmlDoc = xmlhttp.responseXML;

         document.getElementById("FirstName").innerHTML =
         xmlDoc.getElementsByTagName("FirstName")[0].childNodes[0].nodeValue;
         document.getElementById("LastName").innerHTML =
         xmlDoc.getElementsByTagName("LastName")[0].childNodes[0].nodeValue;

      </script>
   </body>
</html>

Output

Save file as nodeattribute_nodevalue.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: Kennedy
LastName: Nkpara
