Re: [Exist-open] Import validation

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

Hi Ted,

Further to Pieter's comment, validation:validate-report() was a function
available in early version of eXist and was deprecated a long time ago,
replaced by validation:parse-report(), validation:jaxv-report() or
valation:jing-report() functions (which is why Michael suggested using a
different function.

When using functions in eXist it is obligatory to check the version you are
using against the documentation. For example, you can search functions here
https://exist-db.org/exist/apps/fundocs/index.html. (although function
documentation is installed automatically in with eXist) You should acquire
the habit of using the terminology of Xquery, functions, as it will help
you search for solutions.

Regards,
JPR
