XML basics

XML, which stands for Extensible Markup Language, is a method of structuring data using special tags.
XML can be used to exchange data between different systems, especially via the Internet.
XML documents that are stored in a file can be used as an alternative to binary files, text files, or even database systems for storing data.
When XML is stored in a file, the file name usually has an extension of xml.
