XML DOM - NamedNodeMap item Method


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 NamedNodeMap item Method.

The NamedNodeMap item method returns the index item in the map. If index is greater than or equal to the number of nodes in this map, then it returns null.

Syntax

The following below is the syntax to use the XML DOM NamedNodeMap item Method -

nodemapObject.item(index)

Parameter Details

S.No.Parameter & Description
1

index

It specifies the position of the item into the map. It is of type unsigned long.


Return Value

It returns the index item in the map.

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 illustrates the usage of the NamedNodeMap item method -

<!DOCTYPE html>
<html>
   <body>
      <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;

         x = xmlDoc.getElementsByTagName('Employee');


         item_name = x.item(0).attributes.getNamedItem("category");
         document.write("Get the specified item value : ")
         document.write( item_name.value );
     </script>
   </body>
</html>

Output

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

Get the specified item value : Technical
