.*? is a "non-greedy" match, meaning it will match shortest possible match, for example if we have sample data:
Code:
<PARTICIPATION_TYPE>BS</PARTICIPATION_TYPE><PARTICIPATION_TYPE>BS</PARTICIPATION_TYPE>

<PARTICIPATION_TYPE>.*?<\/PARTICIPATION_TYPE>will match <PARTICIPATION_TYPE>BS</PARTICIPATION_TYPE>while <PARTICIPATION_TYPE>.*<\/PARTICIPATION_TYPE>would match<PARTICIPATION_TYPE>BS</PARTICIPATION_TYPE><PARTICIPATION_TYPE>BS</PARTICIPATION_TYPE>
$& contains the last match.

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. AUTHOR
