Arrays
... It is possible to obtain the keys (indices) of an array as well as the values. ${!name[@]} and ${!name[*]} expand to the indices assigned in array variable name.

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.
