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.
#! /usr/bin/perl -w
use strict;
use LWP::UserAgent;
my $level = 'Unknown';
my %colors = (
'Unknown' => '#808080',
'Low' => '#63cf63',
'Guarded' => '#009aff',
'Elevated' => '#ffcf00',
'High' => '#ff6500',
'Severe' => '#ff0000',
);
my $userAgent = new LWP::UserAgent;
my $request = new HTTP::Request GET => 'http://www.dhs.gov/dhspublic/g
+etAdvisoryCondition';
my $response = $userAgent->request ($request);
$level = ucfirst lc $1 if $response->is_success &&
$response->content =~ /CONDITION="([^"]*)"/;
print qq{Content-type: text/html
<html>
<body style="background-color:$colors{$level}">
<h3 style="color:#000000">$level</h3>
</body>
</html>
};
exit 0;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
