Re: [Exist-open] Programmatically call the view.xql module

[Jean-Paul R. <re...@gm...>]

Dear Alisdair, is there a reason not to use eXist's triggers?

https://exist-db.org/exist/apps/doc/triggers

ie. store the exterior source in a specific collection -> triggers XSLT
transformation and stores new result (it seems to me any templates you are
using can be rewritten into the transformation Xquery itself and avoid
going through view at all)?

This might allow finer control of each step, particularly when things go
sideways?

Best,
JPR
