Hi,

i have created a database in BaseX GUI but i did not understand how to use it inside FLWR query.

So since i would like to create one FLWR query to query all my files in the database not only one file with doc()

i have tried collection() is that right? (i have putted all my xml files inside path/ directory)

This is my query:

let $d:= collection ("path/")

let $r:= doc("myfile1.xml")

for $d in $d// item/@qcode="tx"

where $d//subj[text() contains text { 'Hal', 'Fade' } any] and $r/subj ="Berlin"

return

it shows me error: [XPTY0019] descendant::subj: node expected, xs:boolean found: false().

what is that error about?

----

Thank you

Best regards
