BSTR name);
Parameters
name[in]
The name of the attribute to be removed or replaced.

E_FAIL

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
