<code>
  #!/usr/bin/perl
use warnings;
use strict;
use Data::Dumper; 
use XML::Simple;
use Template;
my $xml = new XML::Simple;
my $data = $xml->XMLin("data.xml", ForceArray=>['dat','employee','expe
+rience']);

#print Dumper($data);
my $template = Template->new();
my $filename = 'output1.tex';
$template->process(\*DATA, $data, $filename)
    || die "Template process failed: ", $template->error(), "\n";
    
    system( "pdflatex $filename" );
