Some pages of my site are driven by perl cgi scripts. To produce the final
output of these script to the browser, I use XML::LibXML and XML::LibXSLT
to transform some XML (which gets mangled together by the script) into
xhtml via my main output.xsl stylesheet - this is the final stylesheet
from my main AxKit transformation pipeline, which converts my site
specific XML tags into valid XHTML.
I do the output this way to ensure that the perl scripts are producing
output exactly the same as all the AxKit driven pages.
However, since implementing the BasicSession Stuff, I have noticed a
slight problem. The stylesheet I am using, basicly draws all the page
navigation and standard elements etc. One of the standard elements is a
little bit of text which gets displayed in the top left corner of the
page, which shows if you are currently loged in or not. It does this by
checking a parameter which usually gets passed to the stylesheet via the
Apache::AxKit::Plugin::AddXSLParams::BasicSession directive in the
httpd.conf file.
It appears however that when applying the stylesheet to some xml via a
perl script, this paramater is not made available to the stylesheet. My
httpd.conf file looks a bit like this:
<filesMatch "\.(xsp|xml|rdf)$">
PerlModule AxKit
AddHandler axkit .xml .xsp .rdf
...... standard (Axkit bits)
AxAddPlugin Apache::AxKit::Plugin::BasicSession
AxAddPlugin Apache::AxKit::Plugin::AddXSLParams::BasicSession
...etc etc etc..
</filesMatch/>
So is this because I am only applying this axkit stuff to .xsp, .xml and
.rdf files? ie. do I need to include .cgi in there too?
Or do I have to access this parameter directly from the perl script
somehow?
I also wanted to make the perl script set a new session variable and tried
to do this by using the object interface as described on the CPAN pages.
It seemed that I could make the script set up a new AxKit BasicSession
object, and indeed I could set up session variables within this object,
but this object actually had nothing to do with apache - the session
variables I set up in the script were available to the script and only the
script, so when I then moved to another page in the site, the variable I
had set in the perl script had no effect and was not available to any of
my stylesheets/xsp pages.
Any thoughts?
