[Koha-devel] Random XSLT knowledge

[Marcel de Rooy]

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

Marcel

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..
