IXMLDOMDocument::loadXML
The loadXML method loads the supplied string into an XML document.
Syntax
HRESULT loadXML( BSTR bstrXML, VARIANT_BOOL* varIsSuccessful );
Parameters
bstrXML
[in] BSTR containing XML to load into this XML document object. This string can contain an entire XML document or a well-formed fragment.
bIsSuccessful
[out] Pointer to a VARIANT_BOOL indicating whether the load was successful. If the load is unsuccessful, the get_documentElement method of the IXMLDOMDocument interface will return NULL.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
Remarks
Calling load or loadXML on an existing document immediately discards the content of the document. The loadXML method will work only with UTF-8 encodings.
This method is an extension of the World Wide Web Consortium (W3C) Document Object Model (DOM).
Example Code
The following example retrieves a pointer an IXMLDOMDocument interface, and then uses its loadXML method to load the specified XML file.
#include "wmsserver.h"
#include <atlbase.h> // Includes CComVariant and CComBSTR.
// Declare variables.
IWMSServer* pServer;
IXMLDOMDocument* pPlaylist;
HRESULT hr;
VARIANT_BOOL bIsSuccessful;
CComBSTR bstrXML;
// 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);
// Load a sample playlist file.
bstrXML = "<?wsx version \"1.0\" ?><smil> \
<media src = \"welcome1.asf\"/></smil>";
hr = pPlaylist->loadXML(bstrXML, &bIsSuccessful);
EXIT:
// TODO: Release temporary COM objects and uninitialize COM.
if (FAILED(hr)) goto EXIT;
