IXMLDOMElement::removeAttributeNode
The removeAttributeNode method removes the specified attribute from this element.
HRESULT removeAttributeNode(
IXMLDOMAttribute* pDOMAttribute,
IXMLDOMAttribute** ppAttributeNode
);
Arguments
pDOMAttribute |
[in] Pointer to an IXMLDOMAttributeIXMLDOMAttribute Interface representing an attribute that is to be removed from this element. |
ppAttributeNode |
[out] Pointer to a pointer to an IXMLDOMAttribute interface representing an attribute that has been removed from an element. This method calls AddRef internally. To avoid memory leaks, you must call Release when you are finished using the interface. |
Return Value
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
Example
#include “wmsserver.h”
#include <atlbase.h> // Includes CComVariant and CComBSTR.
// Declare variables.
IWMSServer* pServer;
IXMLDOMDocument* pPlaylist;
IXMLDOMElement* pXMLElement;
IXMLDOMAttribute* pXMLAttribute;
IXMLDOMAttribute* pXMLRemoved;
HRESULT hr;
CComBSTR bstrName;
CComVariant varFile;
// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_WMSServer, NULL, CLSCTX_ALL,
IID_IWMSServer, (void**)&pServer);
if (FAILED(hr)) goto EXIT;
// Create the playlist object.
hr = pServer->CreatePlaylist(&pPlaylist);
// Create a media element.
bstrName = "media";
hr = pPlaylist->createElement(bstrName, &pXMLElement);
if (FAILED(hr)) goto EXIT;
// Set the src attribute for the media element.
bstrName = "src";
varFile = "welcome1.asf";
hr = pXMLElement->setAttribute(bstrName, varFile);
if (FAILED(hr)) goto EXIT;
// Retrieve the newly created attribute.
bstrName = "src";
hr = pXMLElement->getAttributeNode(bstrName, &pXMLAttribute);
if (FAILED(hr)) goto EXIT;
// Remove the newly created attribute.
hr = pXMLElement->removeAttributeNode(pXMLAttribute, &pXMLRemoved);
if (FAILED(hr)) goto EXIT;
EXIT:
// TODO: Release temporary COM objects and uninitialize COM.
