JAVA xquery: accessing documents

Hello,

Normally (few basex-versions ago) I did:

But now, this results in basex interpreting the doc()-path as relative to it's home-directory thus cannot find the resource..

"xquery doc("main/users.xml")//users" gives the correct results.

Do we no longer open a database but writing the full path of the document instead?

Whats the performance of this if accessing multiple documents of the same database during runtime?

-regards,

jan

Hi Jan,

In terms of performance, it’s advisable to open the database in advance if you run several commands on it. Otherwise, you can simply address it via XQuery.

If you use fn:doc, the first path segment of the function argument must be the name of your database [1]. db:open will be the safer option, because there won’t be any attempt to find a non-retrievable resource on the local filesystem.

Hope this helps, Christian

Hi Jan (cc to the list),

See the following lines in our documentation:

If the argument of fn:doc or fn:collection does not start with a valid database name, or if the addressed database does not exist, the string is interpreted as URI reference, and the documents found at this location will be returned.

If the DEFAULTDB option is turned on, the path argument of the fn:doc or fn:collection function will first be resolved against the globally opened database.

Hope this helps, Christian
