Simple example of Data::Section and XML::XSLT for Boston.pm

Code:

#!/usr/bin/env perl
use Modern::Perl '2012';
use Data::Dump qw/pp/;

use Data::Section -setup;
use XML::XSLT;

my $xslt_text = ${ main->section_data('XSLT') };
my $xslt = XML::XSLT->new($xslt_text);

foreach my $xml_section ( qw/XML1 XML2/ ) {
    my $xml = ${ main->section_data($xml_section) };
    my $res = $xslt->transform($xml)->toString();

    say "XML $xml_section";
    say $res;
}
