one possible way:

use strict;
use warnings;

my $LOGFILE = "/path/to/logfile/filename.txt";
open(LOGFILE, $LOGFILE) or die "Could not open log file :$!";
while (<LOGFILE>) {
   s/\(\d+\)//g; # remove the (n) part
   s#/([a-z]{2}=)#:::$1#g; # convert delimiter to :::
   my @fields = split(/:::/); #split using new delimiter
   print "$_\n" for @fields;

Probably someone better with regexps can write something shorter and possibly more efficient using zero-width look ahead/behind assertions, which I am not too good with.

$ cat line.txt

perl -nle '(/^(\w+)=(\w+)/&&print "$1=$2")||(/^\w+$/&&print)||(/^\(/ && /(\w+)=(\w+)/&&printf "$1=$2/")foreach split /\//' < line.txt
