About XML

XML (eXtensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.

XML Syntax Rules:

  • XML documents must have a root element
  • XML elements must have a closing tag
  • XML tags are case sensitive
  • XML elements must be properly nested
  • XML attribute values must be quoted

Common uses of XML:

  • Data storage and transport
  • Configuration files
  • Web services (SOAP)
  • Document formats (Office Open XML, SVG)
  • RSS feeds

Well-formed vs Valid XML:

  • Well-formed: Follows basic XML syntax rules
  • Valid: Also conforms to a specific DTD or XML Schema
