About XML

XML (eXtensible Markup Language) is a markup language designed to store and transport data. Unlike HTML, XML does not have predefined tags — you define your own tags.

Common uses include configuration files (Maven, Spring), data exchange (SOAP APIs, RSS feeds), and document formats (DOCX, SVG, EPUB). Well-formed XML must have a single root element, properly nested tags, and attribute values in quotes.
