CGI is pretty simple, and there are many tutorials. Esentially, all the GET form variables are in one environment variable, and POST is up to you to read. All manner of information is passed in environmental variables like the client host and port, what method, etc. Your job is to write the new html less the first line 200 OK to stdout. CGI does not care if you write in shell, PERL (well supported), executable JAVA jar or C/C++, but a non-zero exit will blow off the response. You can log on stderr. Google up a CGI tutorial.

cgi::xml
XML(3pm) User Contributed Perl Documentation XML(3pm)
NAME
CGI::XML - Perl extension for converting CGI.pm variables to/from XML
SYNOPSIS
use CGI::XML;
$q = new CGI::XML;
# convert CGI.pm variables to XML
$xml = $q->toXML;
$xml = $q->toXML($root);
# convert XML to CGI.pm variables
$q->toCGI($xml);
DESCRIPTION
The CGI::XML module converts CGI.pm variables to XML and vice versa.
CGI::XML is a subclass of CGI.pm, so it reads the CGI variables just as CGI.pm would.
METHODS
$q = new CGI::XML
creates a new instance of CGI::XML. You also have access to all of the methods in CGI.pm.
$q->toXML([$root])
where $root is an optional parameter that specifies the root element. By default, toXML will not return a root element.
$q->toCGI($xml)
where $xml is the XML you would like to convert to CGI.pm parameters. Values in the XML will overwrite any existing values if they
exist.
NOTE
CGI::XML does not currently handle multiple selections passed from HTML forms. This will be added in a future release.
