31XML advantages
- Open, platform-independent
- Vocabulary Definitions of TAGS for different
Application Domain - An XML vocabulary is a description of XML data
that is used as the medium for information
exchange, often within a specific domain of human
activity(business, chemistry, law, music, for
example) - Program Readable
- Note XML is not a programming language, nor an
object-based system, nor an operating system. It
is a powerful, elegant technique for thinking
about, exchanging, and presenting data in a
platform-independent manner.
32XML and Browser
- XML changes in internal structure of browsers
- HTML Interpreter ? XML Parser
- A normal Hypertext web-page becomes Application
page - Application Software ? Browser Software
- XML XML data can be processed by application
systems, instead of a browser
