Thanks, that at least fix the "Title of the" problem ;D
so now the expression are:
(?P<author>[^_]+) - (?P<series>[^_]+) (?P<series_index>[0-9]+) - (?P<title>.+) ?
and
(?P<author>[^_]+) - (?P<title>.+) ?
no way to make only one smart enough to skip the series and series index if the filename is xxx -xxx.pdf ?I was looking in something like (?<!...) but I can't figure it out..
Thanks anyway
