Hello folks! welcome back to a new edition of our tutorial on XML DOM. In this tutorial, we will be discussing about the XML DOM Element Object setAttributeNode Method.
The XML DOM setAttributeNode method is used for setting a new attribute node to the existing element.
The XML DOM setAttributeNode method is used for setting a new attribute node to the existing element.
Syntax
The following below is the syntax to use the setAttributeNode method -
elementObj.setAttributeNode(newAttr)
Parameter Details
| S.No. | Parameter & Description |
|---|---|
| 1 | newAttr A new attribute node is added in the attribute list. |
Return Value
This XML DOM method adds a attribute node.
Example
Following 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>Justice</FirstName> <LastName>Douglas</LastName> <ContactNo>1234667898</ContactNo> <Email>justicedauglas@xyz.com</Email> </Employee> <Employee category = "Management"> <FirstName>Stephanie</FirstName> <LastName>Francis</LastName> <ContactNo>1234562350</ContactNo> <Email>stephaniefrancis@xyz.com</Email> </Employee> </Company>
Following example illustrates the usage of the DOM Element Object setAttributeNode method -
<!DOCTYPE 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> xmlDoc = loadXMLDoc("/dom/node.xml"); x = xmlDoc.createAttribute("City"); x.nodeValue = "fourth"; y = xmlDoc.getElementsByTagName("Email"); y[0].setAttributeNode(x); document.write("City attribute is been set at the place: "); document.write(y[0].getAttribute("City")); </script> </body> </html>
Output
Save this file as elementmethod_setattributenode.html on the server's path (this file and the node.xml should be on the same path in your server). This is going to give us the following output below -
Display all the attribute nodes category = technical category = non-technical category = Management
