XML BornXML (Extensible Markup Language) 1.0 standard was published February 10, 1998. XML was born from the shortcomings of SGML [Structured Generalized Markup Language] whichwas hugely complex, massively flexible and just plain hard to work with for many developers. XML has taken off because it has all the best of SGML without many of the weakness.XML GoalXML took us beyond mere presentation of information and into the realm of representationof information. This content is not just a mass of data to be rendered solely for viewingon a web browser. Now the content could be structured and the meaning attached to thisstructure could be transmitted as well.HTMLs difficulties:1- HTML does not reveal anything about the information to which HTML tags are applied.HTML tag names dont describe what content is, they only imply how content appears.For example the html tag "Microsoft" appears on a web browser but HTML can nottell is it a computer corporation? A Software? A Brand name? 2- Web applications relied too much on scripts at the server to process the data. This makes the web slow and contributes to internet traffic.3- You cant add new tags to HTML Language that are meaningful and useful.4- HTML is a presentation technology only.XML SuccessThe Java technology, enables browsers to function as generalized application platforms. The result is True platform independence. XML provides information rich in metadata specifiedin a standard format, XML and Java technology make it possible for more of an applicationswork to be processed at a client side. This contrasts with the tendency of HTML pages to relyon a script back at the server. With XML and Java technology, more client-based application processing could reduce network and internet traffic, making the web faster.XML challengesConverting any information from a display format such as HTML, RTF, MIF, or PostScript to a structured format like XML will require that you understand what your information really contains. This requires a document analysis and the determination of information semantics on which different parts of your enterprise rely. Many enterprises in different business sectors have established industry standard information models that can be expressed in XML and, more importantly, can be shared.Once the relevant information models and their expressions in XML are constructed, the effort to convert existing information into the XML format can proceed. It may or may not be painful,depending on the condition of the existing documents. These efforts can be done in house, or theycan be completed with the help of qualified consultants.XML Resources:Easy XML is a simple XML editor that aids in the rapid building of XML applications.
