Attribute(filename, attributename)
Returns the value of the meta tags of different file formats, e.g. MP3, WMA, WMV and JPG files, as text.
Filename is the name of a media file including path, if needed.
Attributename is the name of a meta tag.
If the file filename does not exist, is not a supported file format or does not contain a meta tag named attributename, null will be returned.
A large number of meta tags can be used, e.g. ‘Artist’ or ‘Date Picture Taken’. The supported tags can automatically be generated in the script.
