HRESULT removeAttributeNode(
IXMLDOMAttribute *DOMAttribute,
IXMLDOMAttribute **attributeNode);
Parameters

C/C++ Example
IXMLDOMElement *pIXMLDOMElement = NULL;
_bstr_t bstrAttributeName = _T("dateCreated");
IXMLDOMAttribute *pIXMLDOMAttribute = NULL;
IXMLDOMAttribute *pRemovedIXMLDOMAttribute = NULL;
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;
if(pIXMLDOMElement)
{
hr = pIXMLDOMElement->getAttributeNode(bstrAttributeName, &pIXMLDOMAttribute);
if(SUCCEEDED(hr) && pIXMLDOMAttribute)
{
hr = pIXMLDOMElement->removeAttributeNode(pIXMLDOMAttribute, &pRemovedIXMLDOMAttribute);
if(SUCCEEDED(hr))
// Attribute node removed.
bResult = TRUE;
pIXMLDOMAttribute->Release();
}
pIXMLDOMElement->Release();
}
// Release pIXMLDOMDocument when finished with it.
}
catch(...)
{
// Release pIXMLDOMDocument if it exists.
if(pIXMLDOMAttribute)
pIXMLDOMAttribute->Release();
if(pIXMLDOMElement)
pIXMLDOMElement->Release();

Remarks
If the attribute has a default value, this call also creates a new attribute with the default value, associates the new attribute with this element, and resets the attribute's specified property.
