regular expresion (clean the spaces)

leria · 04-05-2011, 06:45 AM

sorry , it is my first regular espresion
the type of files are :

series numberofserie - title - author.epub
title - autor.epub

i have made this

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

i want clean the left spaces of title , author and series.
i think i have made it for title and author , but i cant do it in the series , can you help me?
thank you a lot

You need to add parts of the expression to basically suck up the spaces outside of your match groups:

Code:

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

thanks i think it works

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

but i have another problem

file type

serial serialnumber - title - autho.epub

example:
books of films 10 - Rambo - Silvester.epub > ok
books of films 10 - Rambo - Silvester.epub > ok
books of films - Rambo - Silvester.epub > ok
Rambo - Silvester.epub > ok
Rambo - Silvester.epub > ok

BUT
books of films 10 -Rambo - Silvester.epub >fail
if i have more than one space between the numbre and the "-" it fails

after so many changes I'm lost

done
let me know if you see an error

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

thanks a lot

I would think that you could replace \s*(\s-\s) with something like \s*-\s* to allow any number of spaces either side of the dash. The current expression REQUIRES there to be at least one space either side.
