-When IvorySQL achieves compatibility with 11 commonly used XML SQL functions in Oracle 12c, it maintains consistency with PostgreSQL by utilizing the same underlying processing functions, which are provided by the libxml2 library interface. These XML functions are provided as a sub-plugin of the ivorysql_ora plugin, ensuring compatibility and consistency with PostgreSQL databases in terms of XML processing.

 Additionally, to avoid confusion with the existing keyword "extract" in PostgreSQL, IvorySQL has renamed the original keyword to "PGEXTRACT" to ensure clarity and accuracy in function calls.
 
-When implementing these 11 Oracle-compatible XML functions, IvorySQL adopted two different approaches. Among them, besides the UPDATEXML function, the other 10 functions are implemented using SQL functions. Since the number of parameters for the UPDATEXML function is uncertain, an expression-based approach was used for its implementation. This required writing specialized syntax parsing and executor code to ensure the correctness and flexibility of its functionality.
