Converting perl regex to sed regex
I am having trouble parsing rpm filenames in a shell script.. I found a snippet of perl code that will perform the task but I really don't have time to rewrite the entire script in perl. I cannot for the life of me convert this code into something sed-friendly:

Code:
if ($rpm =~ /([a-zA-Z0-9_\-\+]*)-([a-zA-Z0-9_\.]*)-([a-zA-Z0-9_\.]*)\.(.*)/) {
        my $name = $1;
        my $version = $2;
        my $release = $3;
        my $arch = $4;

        ...your code here...

}

(note this is originally from linux engineer's blog and the author states you could simply add "\" before the parens but this still won't work for me.

What would you do?
Any advice is would greatly appreciated. Thank you in advance.

rpmdb

RPMDB(8)						      System Manager's Manual							  RPMDB(8)

NAME

       rpmdb - RPM Database Tool

SYNOPSIS

       rpm {--initdb|--rebuilddb}

DESCRIPTION

       The general form of an rpm rebuild database command is

       rpm {--initdb|--rebuilddb} [-v] [--dbpath DIRECTORY] [--root DIRECTORY]

       Use  --initdb  to create a new database if one doesn't already exist (existing database is not overwritten), use --rebuilddb to rebuild the
       database indices from the installed package headers.

SEE ALSO

       popt(3),
       rpm(8),
       rpmkeys(8),
       rpmsign(8),
       rpm2cpio(8),
       rpmbuild(8),
       rpmspec(8),

       rpm --help - as rpm supports customizing the options via popt aliases it's impossible to guarantee that	what's	described  in  the  manual
       matches what's available.
