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‚ÄĒall of them free open standards‚ÄĒdefine XML. The design goals of XML emphasize simplicity, generality, and usability across the Internet. Read more on Wikipedia...
