About XML Format

Extensible Markup Language (.xml)

XML (Extensible Markup Language) is a flexible, self-describing markup language standardized by the W3C. XML uses custom tags to define data structure and is the foundation for many other formats (DOCX, SVG, XHTML, RSS, SOAP). It supports schemas (XSD), namespaces, XSLT transformations, and XPath queries. XML is widely used in enterprise systems, document formats, configuration files, and data exchange protocols. While JSON has largely replaced XML for web APIs, XML remains essential in publishing (DocBook, DITA), financial services (FIX, XBRL), and government data standards.
