i wrote something similar a while back .

@line = <filehandle> #filehandle used for opening the file

foreach my $line (@lines) {
            
              #note i am matching a line  doing something like printin
+g and then using next ..
              if($line =~/^ProcessName:/){
                $mess = substr $keyword , 13;
                $unirec{$id} .="$date,$id,$mess\n";

                next;
                }
              
              if($line =~/^Process Message :/ ){
                $mess = substr $keyword , 18;
                $unirec{$id} .="$date,$id,$mess\n";

                next;
                }
              
              
       }
