What is XML?

The XML (eXtensible Markup Language) is an extensible markup language similar to HTML but without predefined tags. Users create their own tags suited to their needs. It is an efficient way to store data in a universal format that is easy to search, share, and transfer over a network. The most important advantage of XML is that, the XML format is standardized and widely used. Almost all popular programming languages have built-in modules for parsing and processing XML. XML-formatted data is commonly used in client-server communication across the Internet between different systems.
