Hi David,
Thanks for sharing.
Would you have an example of how you use register_function with Koha functions
to share?
Marcel

Onderwerp: [Koha-devel] Random XSLT knowledge
Hi all,
I’ve been working on performance issues, and in the process I got looking at
XSLTs.
I just wanted to share that it’s possible to pass strings to the XSLT’s
transform() method:
- return $engine->transform($xmlrecord, $xslfilename ); #file or URL
+ return $engine->transform({
+ xml => $xmlrecord,
+ file => $xslfilename,
+ parameters => {
+ test => "'$test_str'",
+ },
+ }); #file or URL
It’s somewhat limited in that you can only pass strings and I think there’s a
small limit on the number of parameters you can pass (not sure if it’s 32 or
255), but I thought it was interesting. It would allow you to pass some data
that you have at hand on a per-XML record basis without having to mangle the
XML record (like we do with items and system preferences).
In the end, I didn’t end up using it though. Instead, I use
XML::LibXSLT->register_function() to provide access to Koha functions from the
XSLT, and in this case that meets my needs.
Anyway, back to it..
