importing PDF with author, title in filename

[autchirion]

Hello,

I have got a problem with importing pdf books to calibre.
Filename: Perry Rhodan 1100 - William Voltz - Der Frostrubin.pdf
rex expresion:
(?P<series>[Perry Rhodan]+) (?P<series_index>[0-9]*) - (?P<author>[^_-]+) - (?P<title>[^_-]+)

Everything looks ok when I test it at the settings.
Title: Der Frostrubin
Author: William Volz
series: Perry Rhodan
Series indes: 1100

But when I start to import my books, it looks like:
Title: Perry Rhodan 1100 - William Voltz - Der Frostrubin
Author: NoMam
.....

After some tests, I had the idea, that it could happen because of the .pdf, so I tested in the settings screen:
Perry Rhodan 1100 - William Voltz - Der Frostrubin

and the output of Calibre was:
Author: unknown
Title, series...: no Math

I´m Using Windows 7 with Calibre 0.7.45, it looks like calibre doesn´t get the .pdf. How can I fix the rex expresion, that it will work or how could I solve my problem?

If you have any questions, feel free to ask! But pleas keep your sentences easy, as you can see, I´m not a native english speaker! :-)

greetings,

I have this syntax working on your example. (?P[^_0-9-]*)\s*(?P[0-9]*)\s*-\s*(?P[^_-]+)?\s*-\s*(?P[^_].+) ? Perry Rhodan 1100 - William Voltz - Der Frostrubin.pdf

I have your file name working with this RegEx

Perry Rhodan 1100 - William Voltz - Der Frostrubin.pdf

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

see if it works for you.

omg... I had to deaktivate "Read metadate from file contents rather than file name", now it works with both of our RegEx...
Thank you verry much for your fast help!

greets, Auti
