Doc-available() function, behavior?
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 $list I'd expect BaseX to return the empty sequence when the document is not in the collection. But Basex returns an error: [basex:doc] Database path 'MyDatabase/bogus-entry.xml' yields no documents. What am I doing wrong? I thought I was following the example in https://docs.basex.org/wiki/Databases#XML_Documents nicely... Thanks in advance!! -- *Arjan Loeffen* Armatiek BV & Armatiek Solutions BV 06-12918997
It seems that in VERSION 9.3 (November 29, 2019) the doc-available($xml-doc) seems to be broken; it should return a boolean but throws an exception. Has this been fixed recently? Cannot find a reference to such a fix in GIT.

Hi Arjan, The bug came in when we changed the error codes of db:open for non-existing documents (maybe that already happened with 9.0.x?). With the latest snapshot [1], fn:doc-available works for database documents again.

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.

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...
Thanks in advance!!
