Code:
$ perl -e '
@xml=<>;
chomp @xml;
$xml=join "",@xml;
@levels=$xml=~m/<add\skey="LevelName"\svalue="#so everything after this should be captured
(.+?)# but in a non-greedy match
"\stype="System.String,mscorlib"\s\/># and only if it is followed by this text
/gx;#the x modifier allows comments in the regex and the g modifier matches all instances
print "We found the following levels in the file:\n";
for $level(@levels){
   print "\t$level\n";
}' ~/tmp.dat
We found the following levels in the file:
        blabla

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
