I'm a tad more proficient with BaseX, but, how do I actually build an XQuery? Yes, I can write an XQuery and save it in a text file, then use BaseX for execution.

But it would be far more flexible to write the actual XQuery from within Java itself. But how?

Oracle gives an example:

OXQDataSource ds = new OXQDataSource(); XQConnection con = ds.getConnection(); String query = "<hello-world>{1 + 1}</hello-world>"; XQPreparedExpression expr = con.prepareExpression(query); XQSequence result = expr.executeQuery();

using their datasource. Cannot BaseX do something similar?
