Re: [Exist-open] library package – load stylesheets into XQuery?

[Julian J. <jul...@ad...>]

Dear Jean-Paul,

Good idea! But that function evaluates to the collection of the XQuery 
which imports the library module. E.g. I’m testing from a script in 
/db/xquery which imports my library. I’ve inserted 
system:get-module-load-path() into the library but still get /db/xquery 
from the testing script.

Nevertheless, rubber ducking this with you got me thinking about this 
section of the documentation

https://exist-db.org/exist/apps/doc/repo#considerations

I adapted the documented code snippet into

util:collection-name(collection('/db/system/repo')//expath:package[@name ="http://www.digitale-akademie.de/cmiferator"])

which works for me! It’s a bit inelegant to hard-code /db/system/repo, 
but repo:get-root() gives me /db/apps. Perhaps I’ll get around to 
optimizing that. For now, I think I’ll test what I’ve already got.

Thanks again!

Best,
Julian
