IsDefault (Compact 2013)
3/26/2014
This interface indicates whether the attribute was specified in the source document or was implied by the Document Type Definition (DTD).
Syntax
BOOL IsDefault ();
Return Value
This interface returns TRUE if the attribute was implied by the DTD. If the attribute was not implied by the DTD or if the node is not an attribute, this interface returns FALSE.
Remarks
Because DTDs only allow for attributes to be defined by using defaults, this property is TRUE for attribute nodes only.
The following code writes all attributes where IsDefault returns FALSE:
HRESULT WriteAttributes(IXmlReader* pReader)
{
const WCHAR* pwszPrefix;
const WCHAR* pwszLocalName;
const WCHAR* pwszValue;
HRESULT hr = pReader->MoveToFirstAttribute();
if (S_FALSE == hr)
return hr;
if (S_OK != hr)
{
wprintf(L"Error moving to first attribute, error is %08.8lx", hr);
return -1;
}
else
{
while (TRUE)
{
if (!pReader->IsDefault())
{
UINT cwchPrefix;
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 (FAILED(hr = pReader->GetValue(&pwszValue, NULL)))
{
wprintf(L"Error getting value, error is %08.8lx", hr);
return -1;
}
if (cwchPrefix > 0)
wprintf(L"Attr: %s:%s=\"%s\" \n", pwszPrefix, pwszLocalName, pwszValue);
else
wprintf(L"Attr: %s=\"%s\" \n", pwszLocalName, pwszValue);
}
if (S_OK != pReader->MoveToNextAttribute())
break;
}
}
return hr;
}
