[C/C++]
C/C++ Syntax
HRESULT removeAttribute( BSTR name);
Parameters
- name [in]
- The name of the attribute to be removed or replaced.
C/C++ Return Values
- S_OK
- The value returned if successful.
- S_FALSE
- The value returned when no attribute with the given name is found.
- E_FAIL
- The value returned if an error occurs.
C/C++ 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
.
