Overview

Image
The main purpose of XML is serialization, i.e. storing, transmitting, and reconstructing arbitrary data. For two disparate systems to exchange information, they need to agree upon a file format. XML standardizes this process. XML is analogous to a lingua franca for representing information.: 1 As a markup languag…

Applications

  • XML has come into common use for the interchange of data over the Internet. Hundreds of document formats using XML syntax have been developed, including RSS, Atom, Office Open XML, OpenDocument, SVG, and XHTML. XML has also provides the base language for communication protocols such as SOAP and XMPP. It is the message exchange format for the …

Key Terminology

  • The material in this section is based on the XML Specification. 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. Character 1. An XML document is a string of characters. Almost every legal Unicodecharacter may appear in an XML document. Processor and application 1. Th…

Characters and Escaping

  • XML documents consist entirely of characters from the Unicode repertoire. Except for a small number of specifically excluded control characters, any character defined by Unicode may appear within the content of an XML document. XML includes facilities for identifying the encodingof the Unicode characters that make up the document, and for expressing characters that, for one reas…

Syntactical Correctness and Error-Handling

  • The XML specification defines an XML document as a well-formedtext, meaning that it satisfies a list of syntax rules provided in the specification. Some key points in the fairly lengthy list include: 1. The document contains only properly encoded legal Unicode characters. 2. None of the special syntax characters such as < and &appear except when performing their markup-delineation role…

Schemas and Validation

  • In addition to being well-formed, an XML document may be valid. This means that it contains a reference to a Document Type Definition(DTD), and that its elements and attributes are declared in that DTD and follow the grammatical rules for them that the DTD specifies. XML processors are classified as validating or non-validatingdepending on whether or not they check XML document…

Related Specifications

  • A cluster of specifications closely related to XML have been developed, starting soon after the initial publication of XML 1.0. It is frequently the case that the term "XML" is used to refer to XML together with one or more of these other technologies that have come to be seen as part of the XML core. 1. XML namespaces enable the same document to contain XML elements and attribu…

Programming Interfaces

  • The design goals of XML include, "It shall be easy to write programs which process XML documents." Despite this, the XML specification contains almost no information about how programmers might go about doing such processing. The XML Infoset specification provides a vocabulary to refer to the constructs within an XML document, but does not provide any guidanc…
