Hi All

I travel along the M62 to get to work and the traffic is a bit of a pain. I wrote this simple LWP script to grab traffic reports from RAC website and pick out those of interest to me.

The code does rely on the structure of the web page not changing which is not the best solution, so if any Monks out there know of a structured source for traffic reports, i'd like to hear from you.

Regards
Orthanc

$req_motorway = ($ARGV[0]) ? $ARGV[0] : "M62|A58";
$req_motorway =~ s/\,/\|/g;

$clear = `clear`;
print "$clear";
print "Getting reports for $req_motorway\n\n";

@html=get("$url");
foreach (@html) { $html .= $_; }
@htmllines = split(/\n/,$html);
%motorways = ();

foreach (@htmllines) {

        if(/bodytextonehead/) {
