I've got an XML file which I'm trying to transform via XSL using LibXML and LibXSL. It prints fine off the command line with the Doc Type and the correct formatting for html but Apache is throwing a 500 error saying that Bad Header = <html>. I know that in CGI you need to change the position of headers but I'm new to Perl and XSLT. 
#!c:\perl\bin\perl.exe

use strict;
use warnings;

use XML::LibXSLT;
use XML::LibXML;

my $parser = XML::LibXML->new();
my $xslt = XML::LibXSLT->new();

my $source = $parser->parse_file('xml');
my $style_doc = $parser->parse_file('xsl');
my $stylesheet = $xslt->parse_stylesheet($style_doc);
my $results = $stylesheet->transform($source);
print $stylesheet->output_string($results);

Is there any way of debugging what the script is sending to the server to see what is being added?
