xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
var myErr = xmlDoc.parseError;
alert("You have error " + myErr.reason);
} else {
nodeBook = xmlDoc.selectSingleNode("//book");
alert(nodeBook.attributes.length);
nodeBook.attributes.removeNamedItem("id");
alert(nodeBook.attributes.length);
}
[Visual Basic]
Visual Basic Syntax
Set objXMLDOMNode = oXMLDOMNamedNodeMap.removeNamedItem(name)
Parameters

If (xmlDoc.parseError.errorCode <> 0) Then
Dim myErr
Set myErr = xmlDoc.parseError
MsgBox("You have error " & myErr.reason)
Else
Set nodeBook = xmlDoc.selectSingleNode("//book")
MsgBox nodeBook.Attributes.length
nodeBook.Attributes.removeNamedItem "id"
MsgBox nodeBook.Attributes.length
End If
