Hi Leo,
this worked like a charm, thank you! (And is also documented in the wiki, shame on me for not seeing this.)

I would like to assign a sequence to a variable and then share this variable between two expressions. Particularly I want to create a list of documents to delete from the db and then return the number of deleted documents.

Is there any way to achieve what I want and put my value in a scope accessible by both expressions?
try this:
let $nodes := ..., $base-uris := $nodes/base-uri(), $distinct-base-uris := distinct-values($base-uris) return ( for $base-uri in $distinct-base-uris return db:delete("db", $base-uri), db:output(count($distinct-base-uris)) )
Hope that helps, cheers, Leo
