Document Actions
XML (Extensible Markup Language) is a meta-language which permits to create markup personalized language.
It has been developed for the first time in 1996 by XML Working Group,
formed under the leadership of the World Wide Web Consortium (W3C).
This text format is placed between SGML (Standard Generalized Markup Language), a very complex meta-language, and HTML (HyperText Markup Language), the markup language used for web pages, built according to SGML specs, too.
This meta-language syntax is simple, clear and clean because, besides being processable by the computer, it is entirely readable even by human users.
Through XML, each user can build a kind of “private HTML”, defining its own tags, as long as these are compatible with general indications.
Moreover standardization is assured by the fact that single users have to respect building metacriteria and to say in a standard format (DTD, Document Type Definition) which kind of tags has been applied in the text and its functionality.
XML is now taken as the standard for text filing in the web, in particular for professional applications allowing a well-constructed indexing and so an accessibility of documents.
This markup language has some functions as the advanced management of links, spread in several functional cathegories, and the creation of stand-alone protocols for the data exchange.
Moreover it can process authomatically the received documents and personalize them, because the structured data can be diplayed thanks to cascading style sheets (CSS), according to the user's choice.
