The XMLTable function in PL/SQL is a powerful feature that allows developers to extract data from XML documents and present it in a tabular format. This function is particularly useful when dealing with XML data in Oracle databases, as it simplifies the process of querying and extracting information from XML documents. Here’s an overview of…(Continue Reading)

In PL/SQL, you can extract data from XML documents by using the XMLType data type and various XML functions. When dealing with nested XML tags, it becomes essential to navigate through the hierarchy of tags to extract the desired information. The XMLTable function is particularly useful for this purpose.
