XML
Extensible Markup Language
A markup language for encoding structured data in a format readable by both humans and machines.
รายละเอียดทางเทคนิค
XML follows a strict tree structure where every element must be properly nested and closed. Namespaces (xmlns) prevent element name collisions when combining vocabularies. DTD (Document Type Definition) and XML Schema (XSD) provide validation against a defined structure. SAX and DOM are the two primary parsing approaches: SAX is event-driven and memory-efficient for large documents; DOM loads the entire tree into memory for random access.
