trigger validation

Dear all,

I want to implement validating a document via a before-update-document trigger.

When validation fails I want the update to fail and I want to provide the caller with feedback.

I wrote this function:


declare function local:validate($uri as xs:string) {
    let $report := validation:jing-report(xs:anyURI($uri), doc("xmldb:exist:///db/apps/corpora/schematron/corpora_linguistics.sch"))
    return if ($report/status='invalid') then
        (
            util:log('warn',$report/message),
            error(QName('http://corpora.fa','invalid'))
        )
    else ()
};

It does the job sort of, but:

  1.  the currently stored document is validated, not the user input
  2.  I found no option to get $report/message back to the user (in eXide)

I could perhaps remember the current document in before-update-document and when validation fails in after-update-document restore the documment, but that seems a bit tricky perhaps.

Does any of you have experience with such a scenario?
