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 item Method.
The item method is used to return the node at the specified index in a node list.
The item method is used to return the node at the specified index in a node list.
Syntax
The following below is the syntax to use the item Method -
Node item(long index)
Return Value
This XML DOM method returns the node at the specified index in a node list.
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 below example is used to parse an xml document (node.xml) into XML DOM object, and displays each item in the node list -
<!DOCTYPE html> <body> <script> if (window.XMLHttpRequest) { xmlhttp = new XMLHttpRequest(); } else { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","/dom/node.xml",false); xmlhttp.send(); xmlDoc = xmlhttp.responseXML; y = xmlDoc.getElementsByTagName("Employee"); for (i=0; i<y.length; i++) { document.write(y.item(i).nodeName); document.write("<br>"); } </script> </body> </html>
Output
Save file as nodemethod_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 -
Employee Employee Employee
