Help removing .txt in this regex.

[Louie Kilmer]

Hi, I'm fairly new to using regular expressions and would appreciate if anyone could help me remove the .txt extensions for this regex

I want to grab just what's in the curved brackets minus the .txt extension of course

/Type /Filespec

/F (filename_to_get.txt)

This is what I have so far: 

#\/Type \/Filespec[\n]\/F \((.*?)\)#

Which is giving me filename_to_get.txt

[Ross Presser]

#\/Type \/Filespec[\n]\/F \((.*?)\.txt\)#

This would match ONLY filenames ending in .txt, and would leave off the .txt in what is grabbed. This might be what you want, of course.  If you wanted to grab ANY three letter extension:

#\/Type \/Filespec[\n]\/F \((.*?)\....\)#
