Hi I need to parse a logfile in which i should do multiline grepping. Logfile: This logfile contains logs of multiple lines.In this file i need to grep three patterns. Eg logfile: Tm500 is tried to execute an attach script. 
rrcConnectionRelease{
         attach request
         measurementReport{
                Event A1
                Id 13
                Purpose
.
.
.
.
.
.
.so on lines

my $logpattern1=rrcConnection;
my $logpattern2=measurementReport;
my $logpattern3=Event;

open(LOGFILE,"$filepath");
my @file=<FILE>;
my $f=join("",@file);
if ($f=~/.*$logpattern1.*?$logpattern2.*?$logpattern3/gs){
 &statuslog("Found log marker : $logpattern1 $logpattern2 $logpattern3
+ in TM500log\n");
                                  
}
else{
&errorlog("Failed to find log marker: $logpattern2 $logpattern3 in $lo
+gpattern1 in TM500log\n");
}


close(LOGFILE);

I had tried this code, its working. But i need a generic way where in i can grep for more than three log patterns. Is it possible to grep these patterns by storing into an array variable? Any help would be appreciated. Thanks in advance
