Regular Expression For Adding Books

jhart711 · 09-27-2010, 01:35 AM

I am trying to work out an expression for adding epub ebooks into Calibre, but I am going around in circles.

I am using this code for files in this format Title - Series - Author.

(?P<title>.+) -? (?P<series>[^_0-9-]*)(?P<series_index>[0-9]*) - (?P<author>[^_].+) ?

But is doesn't work when the series is missing.

Can someone please help?

Code:

(?P<title>((?!\s-\s).)+)\s-\s(?:(?P<series>.+)\s(?P<series_index>\d+)\s-\s)?(?P<author>.+)

Give that a whirl.

I think you got too many whitespaces in there for it to work when the series is missing: You'd have to have three spaces between the title and the author in that case.

That worked perfectly. Thanks.
