I have a data list that gives me coordinates,
but I only want coordinates from specific key words Example:

A red line is found
at location 2.5 4.5
A Blue line is found
at location 2.6 4.5
A red line is found
at location 2.67 4.56
The red arc is found
at location 2.5 4.5

The only data I would want,
is about the "red line".
I was thinking of using the below script,
but I need to look for a key word "red line"
and have it read the line below that line to
get the locations.

Any suggestions? 
 #!usr/bin/perl
use strict;
open FILE, "<$ARGV[0]"; # $ARGV[0] is the file name  
                      # to pass in in the command line.
my $i=1;
while (<FILE>) {
  if ($i >2) { last;}
  print $_ ;
  $i++;
}
close FILE;
