For example: I want to remove the first 4 characters from the Artist title after using the "Filename - Tag" action.
So how would I create an action for that?
To remove the first/last X number of characters.
To remove whatever number of characters from a specific point of a field (for example the first three characters after the first four characters)
Why do you import the number at all? A mask
would only use the string after the dot.
To get rid of the number you can either use an action of the type "Format value" and as format string $mid(%fieldname%,4,$len(%fieldname%))
or an action of the type "replace with regular expression"
Search string: "^\d+. "
(leave out the inverted commas - they should just show you that there is a blank after the dot)
The $mid-function lets you address more or less any position in a string.
