these FLWOR .xq files work as is:
let $db := db:open("com.w3schools.books") for $x in $db/bookstore return $x
or
<new_catalog>{ let $db := db:open("com.w3schools.books") for $x in $db/bookstore/book return <new_book>{$x/title,$x/author}</new_book> }</new_catalog>
Probably a silly question, but, rather than, as in the first query, using $x can I not somehow specify just "/"?
thanks,

nevermind, it's:
let $db := db:open("com.w3schools.books") return $db/bookstore
I thought it was unusual because of db:open.

You would not even need the "let .. return", if you simply want a short expression you can also use
db:open("com.w3schools.books")/bookstore
On top of the query (in the query prolog), you can bind your database to the context. After that, there’ll be no need to bind it to a variable:
declare context item := db:open("com.w3schools.books"); /bookstore

that's interesting. what's item in this example, and how can it be referenced?

Hi thufir,
The specification might be helpful here [1,2], but essentially it is the thing being processed, given as a sort of global scope.
HTH! Best, Bridger
