DOM - Node Object Attribute - nodeValue


Advertisements

The attribute nodeValue is used to specify the value of a node depending on their types.

Syntax

Following is the syntax for the usage of the nodeValue attribute.

nodeObject.nodeValue

Example

node.xml contents are as below −

<?xml version = "1.0"?>
<Company>
   <Employee category = "Technical">
      <FirstName>Tanmay</FirstName>
      <LastName>Patil</LastName>
      <ContactNo>1234567890</ContactNo>
      <Email>tanmaypatil@xyz.com</Email>
   </Employee>
   
   <Employee category = "Non-Technical">
      <FirstName>Taniya</FirstName>
      <LastName>Mishra</LastName>
      <ContactNo>1234667898</ContactNo>
      <Email>taniyamishra@xyz.com</Email>
   </Employee>
   
   <Employee category = "Management">
      <FirstName>Tanisha</FirstName>
      <LastName>Sharma</LastName>
      <ContactNo>1234562350</ContactNo>
      <Email>tanishasharma@xyz.com</Email>
   </Employee>
</Company>

Following example demonstrates 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>

Execution

Save this file as nodeattribute_nodevalue.htm on the server path (this file and node.xml should be on the same path in your server). We will get the output as shown below −

FirstName: Tanmay
LastName: Patil
dom_node_object.htm
