Help!! Having trouble with regular expression

[Partzz]

Here is the file name.

Robert Doherty - Area 51 01 - Area 51.lit

My Problem is some of my series have numbers in the name, and I would like to be able to import with the numbers. For awhile, I lost my expression, and Calibre would not import past the number in the title either. I was able to repair that. Here is what I get with the example file now...

Example:

Title=Area 51 01 - Area 51
Author=Robert Doherty
Series Name=
Series Index=

What I would like to find out is if there is an expression that would seperate the numbers in the series and the series number.

My Current expression is below....

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

Try

(?P<author>.+) - (?P<series>(.+)) (?P<series_index>(.+?)) - (?P<title>.+)

works in the test box.

Thank-you, Thank-you, Thank-you, Thank-you, Thank-you, Thank-you, Thank-you, Thank-you, Thank-you, Thank-you, and Thank-You!!!

I appreciate this. I'm just not getting the hang of the expression language yet!
