Script Syntax
var objXMLDOMAttribute = oXMLDOMElement.XMLDOMElement(DOMAttribute);
Parameters
- DOMAttribute

Return Value
An object. Returns Null unless the new attribute replaces an existing attribute with the same name, in which case this method returns the previous, replaced attribute node.
Example
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0");
var nodeBook, nodePublishDate;
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
var myErr = xmlDoc.parseError;
alert("You have error " + myErr.reason);
} else {
nodePublishDate = xmlDoc.createAttribute("PublishDate");
nodePublishDate.value = String(Date());
nodeBook = xmlDoc.selectSingleNode("//book");
nodeBook.setAttributeNode(nodePublishDate);
alert(nodeBook.getAttribute("PublishDate"));
}
Visual Basic Syntax
Set objXMLDOMAttribute = oXMLDOMElement.XMLDOMElement(DOMAttribute)
Parameters
- DOMAttribute
- An object that contains the attribute node to be associated with this element.
Return Value
An object. Returns Null unless the new attribute replaces an existing attribute with the same name, in which case this method returns the previous, replaced attribute node.
Example
Dim xmlDoc As New Msxml2.DOMDocument50
Dim nodeBook As IXMLDOMElement
Dim nodePublishDate As IXMLDOMAttribute
xmlDoc.async = False
xmlDoc.Load "books.xml"
If (xmlDoc.parseError.errorCode <> 0) Then
Dim myErr
Set myErr = xmlDoc.parseError
MsgBox("You have error " & myErr.reason)
Else
Set nodePublishDate = xmlDoc.createAttribute("PublishDate")
nodePublishDate.Value = Now
Set nodeBook = xmlDoc.selectSingleNode("//book")
nodeBook.setAttributeNode nodePublishDate
MsgBox nodeBook.getAttribute("PublishDate")
End If
C/C++ Syntax
HRESULT setAttributeNode(
IXMLDOMAttribute *DOMAttribute,
IXMLDOMAttribute **attributeNode);
Parameters
- DOMAttribute [in]
- An attribute node that is to be associated with this element.

Remarks
You cannot add an existing attribute to an element until you first remove it from its previous element. Also, you cannot add a namespace-qualified attribute when it uses the same prefix as another attribute with a different namespaceURI.
