[basex-talk] Constructing and querying map structures in a dynamic way

Hello, I would like to construct a map structure based on a dynamic selection by the means of a FLWOR expression. https://www.w3.org/TR/2017/REC-xquery-31-20170321/#id-maps The keys and associated values should be presented as a CSV-like file by a subsequent data processing step. Can it become easier to find existing XQuery script examples for such an use case? Regards, Markus
