Convert XML to 9 (Man Page)

XML, or Extensible Markup Language, is a widely used file extension in computer technology. It is designed to store and transport data, enabling structured information exchange between different systems. XML files are both human- and machine-readable, making them versatile for various applications, including web services, configuration files, and data storage. Originating in the 1990s, XML was developed by the World Wide Web Consortium (W3C) to simplify data interchange and ensure platform independence. Its flexibility and extensibility have made it a standard in many IT environments, fostering seamless integration and data sharing across diverse platforms.

The 9 file extension refers to Section 9 of the Unix manual pages, specifically covering Kernel Routines. These manual pages provide detailed information on kernel APIs, internal structures, and other essential aspects of kernel development. Developed by Dennis Ritchie and Ken Thompson at AT&T Bell Laboratories in 1971, Section 9 is crucial for kernel developers but is not universally available due to its specialized nature.
