File extension xml is commonly used for files written in Extensible Markup Language (XML).

Extensible Markup Language (XML) is a simple, very flexible text format derived from SGML (ISO 8879). Originally designed to meet the challenges of large-scale electronic publishing, XML also plays an increasingly important role in exchanging various data on the Web and elsewhere.

XML is a human-readable, machine-understandable, general syntax for describing hierarchical data, applicable to various applications (databases, e-commerce, Java, web development, searching, etc.).

XML custom tags enable data definition, transmission, validation, and interpretation between applications and organizations.

XML is a subset of SGML and is a metalanaguage providing the rules and conventions to create other languages following these rules. These other languages are called XML-applications.

There are thousands of XML-applications such as MathML (Mathematics Markup Language), CML (Chemical Markup Language), CDF, OSD, HDML (Handheld Device Markup Language), RDF (Resource Description Framework), MML (Music Markup Language)

XML documents can be created with any text-editor just like HTML documents or dynamically by program. XML, however, is much stricter with its rules. XML documents need to be well-formed (e.g. element names, i.e. tags, are case sensitive and must be ended, unlike HTML) and for data vailidity they also need to be valid (i.e. be associated with a DTD which contains definitions of and relationships between elements).
