setAttributeNS method

Browser support:
9
Adds an attribute with the specified namespace, name and value to the current element.
Note: Internet Explorer supports the setAttributeNS method from version 9, but only for HTML documents, not for XML documents.
If an attribute with the same namespaceURI and name exists on the current element, then the setAttributeNS method modifies its value. The namespace and name are case-sensitive.

Syntax:

object.setAttributeNS (namespaceURI, attributeName, attributeValue);

    <script type="text/javascript">
        var httpRequest = null;

            }
            if (httpRequest) {          
                    // The requested file must be in the same domain that the page is served from.
                var url = "ns.xml";
                httpRequest.open ("GET", url, true);    // async
                httpRequest.onreadystatechange = OnStateChange;
                httpRequest.send (null);
