Doc-available() function, behavior?

Van: Arjan Loeffen <arjan.loeffen at armatiek.nl> Date: za 25 apr. 2020 om 17:55 Subject: Doc-available() function, behavior? To: BaseX <basex-talk at mailman.uni-konstanz.de> Dear Basex People, I have this fragment: let $xml-doc := 'MyDatabase/bogus-entry.xml' let $list := *if (doc-available($xml-doc)) then doc($xml-doc)/** else () return $list I'd expect BaseX to return the empty sequence when the document is not in the collection. But Basex returns an error: [basex:doc] Database path 'MyDatabase/bogus-entry.xml' yields no documents. What am I doing wrong? I thought I was following the example in https://docs.basex.org/wiki/Databases#XML_Documents nicely...
