XML

XML (Extensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It is widely used for data interchange between applications, configuration files, and web services, providing a structured way to represent hierarchical data with custom tags.

Also known as: Extensible Markup Language, XML Format, XML Document, XML Schema, XML File

Why learn XML?

Developers should learn XML for scenarios requiring structured data exchange, such as SOAP web services, configuration files in Java or .NET applications, and document formats like RSS or SVG. It is essential in legacy systems, enterprise integrations, and when working with APIs or data formats that mandate XML-based standards.
