[Newbie] Approaches to debugging needed

[Apologies if multiple copies of this message arrive.
The first few times I tried it didn't seem to get
through.]

Hello all,

Perhaps you can help me out. I'm just getting started
with XSL (1.0), and am attempting a fairly simple
XML->HTML transformation. However, I've managed to
break something, and don't know how to approach fixing
it. The rendered output in Firefox and IE is a blank
page. Running it through Saxon produces blank output.
Trying Unicorn, I get:

Document retrieval error:
'file://localhost/C/My%20Documents/XSL/Unicorn/test.xml'
Attempt to reference a node in a context where it does
not exist
    Stylesheet node 'xsl:stylesheet' at line 3
       
(file://localhost/C/My%20Documents/Earle/XML/Unicorn/wiki.xsl)

On the other hand, using the Perl XML::XSLT module to
process it I get the expected output
(http://downlode.org/rdf/wiki/test.html).

I'm at a loss as how to proceed with working out
what's wrong, and would greatly appreciate any advice
you could offer.

The files in question are:
http://downlode.org/rdf/wiki/test.xml and
http://downlode.org/rdf/wiki/wiki.xsl .

Many thanks,

Earle.
