Syntax
BOOL IsEmptyElement ();
Return Value

When writing elements, an XmlNodeType_EndElement node is not generated for empty element start tags.
If the method is not applicable, it will return FALSE.
The following code tests whether the reader is currently on an empty element:
if (FAILED(hr = pReader->GetPrefix(&pwszPrefix, &cwchPrefix)))
{
wprintf(L"Error getting prefix, error is %08.8lx", hr);
return -1;
}
if (FAILED(hr = pReader->GetLocalName(&pwszLocalName, NULL)))
{
wprintf(L"Error getting local name, error is %08.8lx", hr);
return -1;
}
if (cwchPrefix > 0)
wprintf(L"Element: %s:%s\n", pwszPrefix, pwszLocalName);
else
wprintf(L"Element: %s\n", pwszLocalName);
if (FAILED(hr = WriteAttributes(pReader)))
{
wprintf(L"Error writing attributes, error is %08.8lx", hr);
return -1;
}
if (pReader->IsEmptyElement() )
wprintf(L" (empty)");
