Extensible Markup Language, a general-purpose structured text format.
Plain text beginning with the '<?xml' declaration.
XML is a verbose, self-describing text format underpinning countless config files, feeds and document formats (including Office and SVG). It has no binary magic — it is recognized by a leading '<?xml' declaration.
Have a file that might be XML? Identify it with the File Type Identifier — it reads the magic number locally, nothing is uploaded. Or browse all formats.
