Ta funkcja skryptu zwraca wartość metaznaczników różnych plików multimedialnych w postaci tekstu. Obsługiwane są następujące formaty plików: MP3, WMA, WMV, PNG oraz JPG. Jeśli parametr filename pliku nie istnieje, nie jest w obsługiwanym formacie pliku albo nie zawiera metaznacznika o nazwie attributename, zwrócone zostanie NULL.
Attribute(filename, attributename)
Istnieje możliwość odczytu wielu metaznaczników Na przykładach w tym temacie pokażemy, które znaczniki mogą być odczytywane dla odpowiednich obsługiwanych typów plików.
InformacjaMożna odczytać tylko metaznaczniki zapisane w pliku zgodnie z odpowiednią specyfikacją, na przykład ID2v3 dla plików MP3 lub EXIF dla plików JPG, a nie dane znaczników zapisane w Eksploratorze plików w systemie Windows.
Argumenty:
| Argument | Description |
|---|---|
| filename |
Nazwa pliku multimedialnego z ewentualnym uwzględnieniem ścieżki jako połączenie danych w folderze. Przykład: 'lib://Table Files/' |
| attributename | Nazwa metaznacznika. |
W przykładach w celu znalezienia ścieżek do plików multimedialnych używana jest funkcja GetFolderPath. Funkcja GetFolderPath jest obsługiwana tylko w trybie zgodności, dlatego odniesienia do funkcji GetFolderPath należy zastąpić ścieżką połączenia do danych lib://, gdy funkcja jest używana w trybie standardowym lub Qlik Sense SaaS.
