XML::LibXSLT element tags stripped out

[Abro Gaticus]

Being extremely new to XML::LibXSLT and XML/XSL in general I have what
I am assuming is a very newb question.

I found an old post (dated 2001) that showed where to find ppm packages
for libXSLT since I am trying this out using activestate on XP.

C:\> ppm
ppm> set repository RK http://theoryx5.uwinnipeg.ca/p­pmpackages/
ppm> set save
ppm> install XML::LibXML
ppm> install XML::LibXSLT

following these explicit instructions (much appreciated) I was able to
install the packages and begin scripting. The ppm packages are great
as they even download the dll's that XML::LibXSLT depends on.

I created a simple XML file, a simple XSL file, and a simple perl
script that uses XML::LibXSLT to perform the transformation.
Everything seems to work correctly except that in the result document
none of the element tags are output, only their values. <xlsutput
method="xml"/> is ignored. I find this strange as I have read
documentation that 'xml' should be the default output method anyway.

Perhaps someone can suggest what I am doing incorrectly. Code below:
Thanks in advance.

--------------------------------
test.xml:
<?xml version="1.0" ?>

<entry>
<major>
pain in the grass
</major>
<stats>
<a> 11 </a>
<b> 21 </b>
<c> 31 </c>
<d> 41 </d>
<e> 51 </e>
</stats>
</entry>

-------------------------------
template.xsl
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xslutput method="xml"/>

<!-- first attempt -->
<xsl:template match="stats">
<xsl:text> Stats: </xsl:text>
<xsl:apply-templates/>
</xsl:template>

</xsl:stylesheet>

---------------------------------
result.xml
<?xml version="1.0"?>

Stats:

---------------------------
xslTest.pl
use strict;
use XML::LibXSLT;
use XML::LibXML;

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

my $source = $parser->parse_file('test.xml');
my $style_doc = $parser->parse_file('template.xsl');

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

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

$stylesheet->output_file($results,'result.xml');

It is, and not a Perl one - it is a pure XSL one.

I created a simple XML file, a simple XSL file, and a simple perl
script that uses XML::LibXSLT to perform the transformation.
Everything seems to work correctly except that in the result document
none of the element tags are output, only their values.

This is the effect of the default XSL trasformation.

<xlsutput
method="xml"/> is ignored. I find this strange as I have read
documentation that 'xml' should be the default output method anyway.

AFAIK, it is.

You are wrongly assuming that the default XSL transformation is the
identity transformation.

Read about the default XSL tranformation here:

http://www.w3.org/TR/xslt#built-in-rule

If you want to copy elements you need to add an explicit template to do so.
