About XML (Extensible Markup Language)
XML is a flexible markup language designed for storing and transporting structured data. While more verbose than JSON, XML offers namespaces, schemas, and transformation support (XSLT) that make it essential in enterprise systems, document formats (DOCX, SVG), and legacy integrations.
Strengths
- ✓ Self-describing with schemas (XSD)
- ✓ Namespace support for complex documents
- ✓ Transformation via XSLT
- ✓ Validation and strong typing
Limitations
- • More verbose than JSON or YAML
