<p>Displays the Department of Homeland Security threat level, in color. This was just a little CGI I wrote to make a point. Note that I do not advocate parsing XML with regular expressions, except in trivial cases like this.

my $userAgent = new LWP::UserAgent;
my $request = new HTTP::Request GET => 'http://www.dhs.gov/dhspublic/getAdvisoryCondition';
my $response = $userAgent->request ($request);

$response->content =~ /CONDITION="([^"]*)"/;
