What is XML?
XML (Extensible Markup Language) is a markup language that encodes documents using nested tags with attributes, similar to HTML but for arbitrary structured data. It supports namespaces, schemas (XSD), and validation, which is why it is still common in enterprise, SOAP, and configuration formats where strict document structure matters.
