About
Extensible Markup Language (XML) is a markup language and file format for storing, transmitting, and reconstructing structured data in a platform-independent way.
It uses a hierarchical tree structure with custom-defined tags, supports schemas such as DTD and XML Schema for validation, enables namespaces to avoid naming conflicts, and is widely used in formats and protocols such as 
RSS, SOAP, and configuration files.
