JScript Syntax
var objXMLDOMAttribute = oXMLDOMElement.XMLDOMElement(DOMAttribute);
Parameters
DOMAttribute
An object that contains the attribute node to be associated with this element.
Return Value

Example
Note
You can use books.xml to run this sample code.
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.6.0");
var nodeBook, nodePublishDate;
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
var myErr = xmlDoc.parseError;
WScript.Echo("You have error " + myErr.reason);
} else {
nodePublishDate = xmlDoc.createAttribute("PublishDate");
nodePublishDate.value = String(Date());
nodeBook = xmlDoc.selectSingleNode("//book");
nodeBook.setAttributeNode(nodePublishDate);
WScript.Echo(nodeBook.getAttribute("PublishDate"));
}
Output
Outputs the current date and time in the following format:

IXMLDOMAttribute **attributeNode);
Parameters
DOMAttribute[in]
An attribute node that is to be associated with this element.
attributeNode[out, retval]
Null unless the new attribute replaces an existing attribute with the same name, in which case this method returns the previous, replaced attribute node.
Return Values
S_OK
The value returned if successful.
