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?

This example is based on the XQJ API. Have a look at [1] to see how it is used in BaseX (and what other APIs exist).

Written for BaseX 9.1. BaseX may have changed since: please check the current documentation.
