Esta función de script devuelve el valor de las meta etiquetas de diversos formatos de archivo como texto. Están disponibles los siguientes formatos de archivo: MP3, WMA, WMV, PNG y JPG. Si el archivo filename no existe, no se admite como formato de archivo o no contiene una metaetiqueta con el nombre attributename, se devuelve NULL.
Attribute(filename, attributename)
Se pueden leer un gran número de metaetiquetas. Los ejemplos de esta sección muestran qué etiquetas se pueden leer para los respectivos tipos de archivo admitidos.
Nota informativaSólo podemos leer meta etiquetas guardadas en el archivo conforme a la especificación relevante, por ejemplo ID2v3 para archivos MP3 o EXIF para archivos JPG y ninguna información meta que se haya guardado en el Explorador de archivos de Windows (Windows 7) o el Explorador de archivos (Windows 8.1 y 10).
Argumentos:
- filename: El nombre de un archivo de medios con la ruta incluida, si fuera necesario.
-
absolute
Ejemplo: c:\data\
-
relativo a la ruta del documento QlikView.
Ejemplo: data\
- attributename: Es el nombre de una meta etiqueta.
