问题 I am working with eXist-db 4.2.1 and Xquery 3.1 using the eXist's default installation of controller.xql and view.xq . I have a document.html to which I pass any incoming url structured with /doc/some-requested-doc-id at the end to produce a dynamically-created page based on some-requested-doc-id . So, the incoming url can be either http://localhost:8080/exist/apps/deheresi/doc/MS609-0001 or http://localhost:8080/exist/apps/deheresi/doc/MS609-0001.xml and they are treated the same... In the

问题 Both JSONiq and XQuery 3.1 extend XQuery 3.0 with support for JSON.

JSONiq was designed with the goal of querying and updating JSON in settings such as document stores. It was also designed by members of the XML Query working group

问题 I'm new to XQuery in SQL but I'm understanding the basics of getting nodes and the values of the queries. My issue now is handling a hierarchy of unknown depth.
