Repository navigation
Querying a document collection does not seem to return non-XML files #18
Description
I'm running the Alpha 3 Docker instance.
I'm finding that I can't see the PDF files I have installed alongside my XML documents.
This had worked fine with eXist-db and I've changed nothing other that switch to the FusionDB instance.
My simplified xquery is:
xquery version "3.1";
declare namespace d="DAV:";
for $doc in collection('/repository/grantcv1')
return (
let $fileURI := base-uri($doc)
return <d:response xmlns:d="DAV:">
<d:href>{$fileURI}</d:href>
</d:response>
)
I get all the XML files, but nothing else. I used to get the complete list of files in the folder.

The behavior you see in eXist was true for eXist 5.2.0 and lower, but with eXist-db/exist#3349, the next release of eXist will match the behavior you see in FusionDB. The change was to ensure
fn:collection()function would return properdocument-node()nodes (containing XML data, not binary data). As an alternative for your use case, considerxmldb:get-child-resources().adamretter commentedon Mar 7, 2021
Thanks @joewiz. @grantcv1 The change was made so that FusionDB (and eXist-db) become more compliant with the W3C XQuery specifications. There is some explanation and details in the issue that Joe referenced.
For returning a list of URI as your query above is shown, it is actually more efficient to use
xmldb:get-child-resourcesas suggested by Joe.I hope that helps? Let us know if you need any more support in this area.
