Thanks Leonard and Christian!!! I have solved it using

final QueryProcessor processor = new QueryProcessor("doc('"+workspace + "\cabecera.xml')"+query, CONTEXT);

I don't need to create databases and drop them if i only want to get data, understood :)

BaseX team is wonderful, thanks!!!

Hi Bea,

i didn't realize that you're not on the basex-talk list. Sorry for that.

Hi again,

Just in case you're interested: A simple way to create a main-memory based DB in BaseX, given the path to an XML document, would be

final Data db = CreateDB.xml(IO.get(path), CTX.prop); CTX.openDB(db); // open DB in current Context

By the way, this also works if you feed IO.get(..) an XML string instead of a path.

Cheers again, Leo

Hello Beatriz,

wouldn't it be much easier to use an in-memory DB in this case? No need to explicitly drop it and you probably would even get better performance because of reduced I/O.

Just my 0.02$...
