Trouble with AxKit at runtime - XML parsing stage
Being seduced by the proud anouncements Matt made here, and seeing the axkit
and take23 sites,
I decided to play with AxKit myself.
I have installed AxKit according to the AxKit(3) manpage, and (I think)
configured apache to load it.
It uses sablotron 0.44 and the latest expat from sourceforge - 1.95.1 below
it.
All the dependent modules (like XML::Sablotron and XML::Expat) and AxKit
itself were reporting 100% test success.
CPAN reports all dependencies are up-to-date.
I have been unable, however, to render smth very basic with it, with just
XML+XSL test (I haven't yet come to XPath games).
0) Please pardon my q(2) in case of my XML/XSL fault - I have never used XSL
before today, and perhaps I omitted smth basic. My bg comes from DSSSL/SGML
and every time I look at XSL I am thinking first of an associated DSSSL
stuff, then locating the appropriate tag in the XSL spec, then writing XSL.
1) My 1st problem, however, is smth to deal with Apache<->mod_perl<->AxKit
interaction at configs read time.
It's a minor problem, and I have a workaround (see below), so you can just
skip down to (2). But I just hoped some of the mod_perl gurus around may
have some clue here.
I have tried 1st to place just
PerlModule AxKit
<Location /x>
AllowOverride All
</Location>
into the apache httpd.conf,
and
# Install AxKit main parts
SetHandler perl-script
PerlHandler AxKit
# Setup style type mappings
AxAddStyleMap text/xsl Apache::AxKit::Language::Sablot
AxAddStyleMap application/x-xpathscript \
Apache::AxKit::Language::XPathScript
# Optionally set a hard coded cache directory
# make sure this is writable by the web server runtime user/group
AxCacheDir /usr/local/apache/htdocs/x/cache
into .htaccess under htdocs/x
It doesn't get to AxKit that way, despite AllowOverride All!
However, if I paste the contents of htdocs/x/.htaccess just before the
aforementioned </Location> in the global conf file, everything is fine in
the sense that the perl handler gets installed. I didn't find anything
similar mentioned in Stas' guide - am I missing smth obvious, or has it smth
to do with AxKit in general or as installed here?
2) In the case of the worked around (1), here's what I get for a tiny test
case in the error log:
[AxKit] : handler called for /x/test.xml
[AxKit] : checking if we process this resource
[AxKit] : media: screen, preferred style: #default

</xsl:stylesheet>
I did check both for well-formedness with nsgmls, and both produce precicely
the ESIS I'd expect them to.
Can you please give some advice? An RTFM link would be appreciated as well.

Thanks, Matt!
It has been built out of the box.
I am going to play with it now...

Yes, it is. Please use AxKit 1.1-pre.

Ahh, my mistake thanks for the clarification.

The latest version of 5.6 _is_ 5.6.0. The bizarre copy thing is fixed in
CVS and 5.6.1 should incorporate this change.

I believe that the Bizzar copy of array problem is related to a bug in
Perl 5.6 that was patched a while ago.
Make sure you are running the latest version of perl5.6
Also there is an AxKit users mailing list that you can post these
questions to:
axkit-users@axkit.org
