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.
