[Matt Sergeant <matt sergeant org>]

Slight bug in document("") perhaps?

Ok, I found the offending part:

  #!perl -w
  use strict;
  use warnings;
  use XML::LibXML;
  use XML::LibXSLT;
  use Data::Dumper;

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

  my $source = $parser->parse_file('r.xml');
  my $style_doc = $parser->parse_file(q(e:\ym\example\2\l2l.xslt));
  #                                     ^^^^^^^^^^^^^^^^^^^^^^^^

  my $stylesheet = $xslt->parse_stylesheet($style_doc);

  my $results = $stylesheet->transform($source);

  print $results->toString;

Using a relative path like 'l2l.xslt' or slashes in the path like
'e:/ym/example/2/l2l.xslt' it works, but using the path above,
document("") returns an empty node set, while the rest of the style
sheet works as expected.
