In computing, Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The W3C’s XML 1.0 Specification and several other related specifications—all of them free open standards—define XML.
The design goals of XML emphasize simplicity, generality, and usability across the Internet. It is a textual data format with strong support via Unicode for different human languages. Although the design of XML focuses on documents, the language is widely used for the representation of arbitrary data structures such as those used in web services.
Several schema systems exist to aid in the definition of XML-based languages. A DTD is an example of a schema or grammar. Schema languages typically constrain the set of elements that may be used in a document, which attributes may be applied to them, the order in which they may appear, and the allowable parent/child relationships.
A newer schema language is XML Schema, often referred to by the initialism for XML Schema instances, XSD (XML Schema Definition). XSD’s are far more powerful than DTDs in describing XML languages. They use a rich data typing system and allow for more detailed constraints on an XML document’s logical structure. XSD’s also use an XML-based format, which makes it possible to use ordinary XML tools to help process them.
XSL (Extensible Stylesheet Language) is a family of languages used to transform and render XML documents, split into three parts:
