Example
Following are the node_ns.xml contents -
<?xml version = "1.0"?> <Company> <Employee xmlns:e = "http://www.webdesigntutorialz.com/technical/" category = "technical"> <e:FirstName e:lang = "en">Kennedy</e:FirstName> <e:LastName>Nkpara</e:LastName> <e:ContactNo>1234567890</e:ContactNo> <e:Email>kennedynkpara@xyz.com</e:Email> </Employee> <Employee xmlns:n = "http://www.webdesigntutorialz.com/non-technical/" category = "non-technical"> <n:FirstName n:lang = "en">Stephanie</n:FirstName> <n:LastName>Francis</n:LastName> <n:ContactNo>1234667898</n:ContactNo> <n:Email>stephaniefrancis@xyz.com</n:Email> </Employee> </Company>
Following example illustrates the usage of the DOM Element Object removeAttributeNS method -
<!DOCTYPE html> <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_ns.xml"); x = xmlDoc.getElementsByTagName("FirstName")[0]; ns = "http://www.webdesigntutorialz.com/technical/"; document.write("Before removing the attributeNS: "); document.write(x.getAttributeNS(ns,"lang")); x.removeAttributeNS(ns,"lang"); document.write("<br>After removing the attributeNS: "); document.write(x.getAttributeNS(ns,"lang")); </script> </body> </html>
Output
Save this file as elementmethod_removeattributens.html on the server's path (this file and node_ns.xml should be on the same path in your server). This is going to give us the following output below -
Before removing the attributeNS: en After removing the attributeNS: null
