Oracle PL/SQL provides powerful features for handling XML data, making it convenient to process XML files directly within your database environment. Whether you need to extract data from XML files or integrate XML data into your database workflows, PL/SQL offers the tools to accomplish these tasks efficiently.

Here's a step-by-step guide on how to read an XML file in Oracle PL/SQL:

Create Directory Object:
First, you need to create a directory object in your Oracle database to point to the location where your XML file is stored. This step allows PL/SQL to access the XML file from the specified directory.
