Programmatic Export of Single Report Definition

In this scenario, instead of using `export_file_data` for a bundled export, you should use the function `XXEN_API.export_report_` inside a PLSQL loop. This function accepts a single parameter, `p_report_id`, and returns the report XML as a CLOB.

When integrating this into a script with `dbms_xslprocessor.clob2file`, you can sanitize the report name using a function like `xxen_report.space_to_underscore(c.report_name)` to create a valid filename.
