i am trying to write a code to find two pattern from one file sequentially. while the code is running but only i am getting one pattern and not the second pattern. when i have added a print statement in second loop it shows n time "into the second loop.." print for the same no of times as n as no of lines in the file but not the second pattern 

opendir( my $synthdir,$target_dirsynth1) or die "Couldn't enter config
+ directory: $!\n";
          print("\nSYNTHESIS INPUT FILES IN CURRENT DIRECTORY \n");
          my $synthfilelist = glob "*.qsf";
          print ("\n$synthfilelist \n");

       my $originalquartus ;
       my $latestquartus ;
       my $readlineqo;
       my $readlineql ;

open (my $OFILE,$synthfilelist) || die "couldnt open file: $!";  
   while ($readlineqo = <$OFILE>) {
       chomp $readlineqo;
       if ($readlineqo =~ /ORIGINAL_QUARTUS_VERSION/) { 
       my @originalqarray = (split / +/ , $readlineqo);
       $originalquartus = $originalqarray[3];
       print "\nthe original quartus $originalquartus\n";
         }
     next if $readlineqo =~ /^ $/;
       }
   close($OFILE); 

open (my $LFILE,$synthfilelist) || die "couldnt open file: $!";  
   while ($readlineql = <$LFILE>) {
       chomp $readlineql;
       print "into the second loop $readlineql\n";
       if ($readlineql =~ /LAST_QUARTUS_VERSION/) { 
       my @latestqarray = (split / +/ , $readlineql);
       $latestquartus = $latestqarray[3];
       print "\nthe latest quartus $latestquartus\n";
       }
     next if $readlineql =~ /^ $/;
      }       
   close($LFILE);
