Hello together, I just recently startet using BaseX in one of my Projects and since I was developing on the GUI of BaseX I had no Problems with anything. Unfortunately, for reasons, I need to use the Saxon Processor to Query my BaseX DB. I tried different approaches, but, everything endet up with the following error message: XPST0017: Saxon does not allow external function to be declared The query I tried looks as followed: xquery version "3.0"; declare namespace vm = "http://www.viamedici.de"; import module namespace db = "http://basex.org/modules/db" at "test/db.xqm"; (: Retrieve documents from database :) db:open("hades")//template Since I could not get usable information from google I hope some of you guys can help me. Thanks a lot, Jörn Jörn Uli Goeke Projektleiter / Projektentwickler Viamedici Software GmbH Hertzstr. 14 D-76275 Ettlingen Germany Phone: +49(0)7243/9498-36 Fax: +49(0)7243/9498-99 e-mail: j.goeke@viamedici.de URL: www.viamedici.de<http://www.viamedici.de> HRB 362615, Amtsgericht Mannheim Geschaeftsfuehrer: Juergen Mueller
