Using an XML configuration file for Log::Log4perl

XML configuration file:

<!--
* General configuration for log4perl
* LOGFILE.filename may be set by the application
* All logging goes to STDOUT (CONSOLE)
-->
<log4perl>
<log4perl.rootlogger>WARN, CONSOLE, LOGFILE</log4perl.rootLogger>

<log4perl.appender.console>Log::Log4perl::Appender::Screen</log4perl.appender.CONSOLE>
<log4perl.appender.console.layout>PatternLayout</log4perl.appender.CONSOLE.layout>
<log4perl.appender.console.layout.conversionpattern>[%d] [%p %c] - %m%n</log4perl.appender.CONSOLE.layout.ConversionPattern>

<log4perl.appender.logfile>Log::Log4perl::Appender::File</log4perl.appender.LOGFILE>
<!-- Let logging come to STDERR on the console, and *pipe* into a log so that unexpected errors are caught
<log4perl.appender.logfile.filename>/optional/absolute/path/to/logfile.log</log4perl.appender.LOGFILE.filename>
-->
<log4perl.appender.logfile.mode>append</log4perl.appender.LOGFILE.mode>

How to read the configuration:

my $log4perl = XML::Simple->new(ForceArray=>0, KeyAttr=>[])->XMLin( $log4perl_config_filename );
my $logname = $0;
$logname =~ s/\.pl$/.log/;
$log4perl->{'log4perl.appender.LOGFILE.filename'} = $logname;
Log::Log4perl::init($log4perl);
my $logger = Log::Log4perl->get_logger(__PACKAGE__);
