The processor (as the specification calls it) is often referred to colloquially as an XML parser. The specification places requirements on what an XML processor must do and not do, but the application is outside its scope. Processor and application The processor analyzes the markup and passes structured information to an application. Every legal Unicode character (except Null) may appear in an (1.1) XML document (while some are discouraged). This is not an exhaustive list of all the constructs that appear in XML it provides an introduction to the key constructs most often encountered in day-to-day use.Ĭharacter An XML document is a string of characters. The material in this section is based on the XML Specification. XML is used extensively to underpin various publishing formats. In publishing, Darwin Information Typing Architecture is an XML industry data standard. Many industry data standards, such as Health Level 7, OpenTravel Alliance, FpML, MISMO, and National Information Exchange Model are based on XML and the rich features of the XML schema specification. It is the message exchange format for the Asynchronous JavaScript and XML (AJAX) programming technique. XML also provides the base language for communication protocols such as SOAP and XMPP. Hundreds of document formats using XML syntax have been developed, including RSS, Atom, Office Open XML, OpenDocument, SVG, COLLADA, and XHTML. XML has come into common use for the interchange of data over the Internet. RFC 7303 further recommends that XML-based languages be given media types ending in +xml, for example, image/svg+xml for SVG.įurther guidelines for the use of XML in a networked context appear in RFC 3470, also known as IETF BCP 70, a document covering many aspects of designing and deploying an XML-based language. They are used for transmitting raw XML files without exposing their internal semantics. It defines three media types: application/xml ( text/xml is an alias), application/xml-external-parsed-entity ( text/xml-external-parsed-entity is an alias) and application/xml-dtd. IETF RFC 7303 (which supersedes the older RFC 3023), provides rules for the construction of media types for use in XML message. (This is also referred to as the canonical schema.) : 135 An XML document that adheres to basic XML rules is "well-formed" one that adheres to its schema is "valid." : 135 : 11 An additional XML schema (XSD) defines the necessary metadata for interpreting and validating XML. What's within the tags is data, encoded in the way the XML standard specifies. : 11 XML tags represent the data structure and contain metadata. : 1Īs a markup language, XML labels, categorizes, and structurally organizes information. It is therefore analogous to a lingua franca for representing information. For two disparate systems to exchange information, they need to agree upon a file format. storing, transmitting, and reconstructing arbitrary data. The main purpose of XML is serialization, i.e. Several schema systems exist to aid in the definition of XML-based languages, while programmers have developed many application programming interfaces (APIs) to aid the processing of XML data. 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. It is a textual data format with strong support via Unicode for different human languages. The design goals of XML emphasize simplicity, generality, and usability across the Internet. The World Wide Web Consortium's XML 1.0 Specification of 1998 and several other related specifications -all of them free open standards-define XML. It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.
