Hey,
Thanks for the quick reply!
I decided to do a simple query using basex:db(), and its results are... odd. Simply performing:
for $doc in basex:db('yourdb') return $doc
only returns the first document in my database. I thought maybe the database was corrupt or something, so I tried:
for $doc in /my_root_node return $doc
And that returned the entire structure of all documents in the database.
Is that the normal functionality of basex:db()? If so, then I can not iterate through it as per your examples, since it will only see the first document.
