how to split file by two new lines (\n\n) and convert it into array Input file example:

Status_EventId = ""
Status_NmosSerial = ""
Status_Acknowledged = 0
acknowledgementStatus = "notAck"
additionalText = ""
specificProblems00 = ""
managedobjectInstance00 = "1.3.6.1.4.1.12.2.2.159#1/1.3.6.1.4.1.12.2.2

additionalInfo00 = "RMServiceState =notInService"
additionalInfo01RMObjectType = "lo-hotrail"
notificationType = "alarmRaise"
remoteHost = "/10.23.13.153:25061"
eventType = "communicationsAlarm"
eventTime = "20140818050646"
ASid = "3"
firstOccurence = "1408338596741"
probableCause = "Transport Failure"
reservationStatus = "notReserved"
friendlyName = "Trail_S42.3_S42.6_01"
RawCaptureTimeStamp = 1408338596

Output data format should be as below:

additionalInfo00,notificationType,eventType,friendlyName
"RMServiceState =notInService","alarmRaise","communicationsAlarm","Tra
+il_S42.3_S42.6_01"

The output file should has header and then data from the input file. I am not able to split file into array and assign vlaues to the keys in desired format. Kindly help me

use strict;
use warnings;

my $fname="file55.txt";

print "additionalInfo00,notificationType,eventType,friendlyName\n";
open my $f,"<",$fname or die "Cannot open $fname : $!";
local $/= "\n\n";

while (my $event =<$f>){
  my %info;
  my @lines = split /\n/,$event;
  for (@lines){
     chomp;
     next unless my ($k, $v)=/(\S+) = (.+)/;
     $v=~s/^\s*"//;
     $v=~s/"?\s*$//;
     $info{$k} = $v;
  }
  $info{additionalInfo00} or next;
  print "\"", 
    join('","', map {$info{$_}} qw|additionalInfo00 notificationType e
+ventType friendlyName|)
    ,"\"\n";
  
}

Output:

additionalInfo00,notificationType,eventType,friendlyName
"RMServiceState =inService","alarmRaise","communicationsAlarm","B_GSM-
+R_N0a.12_N11BSC2.01"
"RMServiceState =notInService","alarmRaise","communicationsAlarm","Tra
+il_S42.3_S42.6_01"
