Hi! I'm a new Sedna user, programming in Scheme on a MacOS X computer.
I'm having a problem accessing the se:get-property function, as
described in http://modis.ispras.ru/sedna/progguide/ProgGuidesu8.html.
I have a function that enables me to execute arbitrary XQuery query
strings (it's a modification of a function known to work):
;--------------------------
(define (infoml:run-XQuery-query2 the-query)
(sedna:begin-transaction *infoml:Sedna-connection*)
(let* ((prefix "declare namespace se = 'http://
www.modis.ispras.ru/sedna';\n")
(result (sedna:result->list
(sedna:execute-query *infoml:Sedna-connection*
(string-append prefix the-query)))))
(sedna:end-transaction *infoml:Sedna-connection* 'COMMIT)
result))(define (infoml:run-XQuery-query2 the-query)
(sedna:begin-transaction *infoml:Sedna-connection*)
(let* ((prefix "declare namespace se = 'http://
www.modis.ispras.ru/sedna';\n")
(result (sedna:result->list
(sedna:execute-query *infoml:Sedna-connection*
(string-append prefix the-query)))))
(sedna:end-transaction *infoml:Sedna-connection* 'COMMIT)
result))
;--------------------------
When I execute various queries, I get two different error codes:
;--------------------------
> (infoml:run-XQuery-query2 "se:get-property($documents as xs:string)
as item();")
uncaught exception: ((#<procedure:condition?> (exn message "Server
reported of an error: SEDNA Message: ERROR XPST0003\nIt is a static
error if an expression is not a valid instance of the grammar defined
in A.1 EBNF.\nDetails: unexpected token: 'as', line: 2\n")))
> (infoml:run-XQuery-query2 "se:get-property($documents);")
uncaught exception: ((#<procedure:condition?> (exn message "Server

> (infoml:run-XQuery-query2 "se:get-property($documents)")

;--------------------------
As you can see, I am unsure as to whether the query string needs to
end with either a semicolon or "\n", but neither seems to be the root
cause of the error.
What am I doing wrong? Thank you for taking the time to respond.
