I have a text that looks like this. What I want to do is

  1. to extract the whole paragraph under the section "Aceview summary" until the line that starts with "Please quote".
  2. extract the line that starts with "The closest human gene".

And store them into array with two elements.

However I am stuck with the following script logic. What's the right way to achieve that?

   #!/usr/bin/perl -w

   my  $INFILE_file_name = $file;      # input file name

    open ( INFILE, '<', $INFILE_file_name )
        or croak "$0 : failed to open input file $INFILE_file_name : $!\n";


    my @allsum;

    while ( <INFILE> ) {
        chomp;

        my $line = $_;

        my @temp1 = ();
        if ( $line =~ /^ AceView summary/ ) {
            print "$line\n";
            push @temp1, $line;
        }
        elsif( $line =~ /Please quote/) {
            push @allsum, [@temp1];
             @temp1 = ();
        }

    }

    close ( INFILE );           # close input file
