Example

IXMLDOMElement *pIXMLDOMElement = NULL;
_bstr_t bstrAttributeName = _T("dateCreated");
IXMLDOMDocument *pIXMLDOMDocument = NULL;
HRESULT hr;

try
{
   // Create an instance of DOMDocument and initialize pIXMLDOMDocument.
   // Load/create an XML fragment.
   hr = pIXMLDOMDocument->get_documentElement(&pIXMLDOMElement);
   SUCCEEDED(hr) ? 0 : throw hr;

   hr = pIXMLDOMElement->removeAttribute(bstrAttributeName);
   if(SUCCEEDED(hr))
   {
   // Attribute removed.
   }
   pIXMLDOMElement->Release();
   pIXMLDOMElement = NULL;
   // Release pIXMLDOMDocument when finished with it.
}
catch(...)
{
   // Release pIXMLDOMDocument if it exists.
   if(pIXMLDOMElement)
      pIXMLDOMElement->Release();
   DisplayErrorToUser();
}

Remarks

If the specified attribute has a default value, this is equivalent to a replace operation: The current value is removed and a new attribute is created with the default value. This operation also resets the specified property of IXMLDOMNode.

Versioning

Implemented in: MSXML 3.0 and MSXML 6.0
