XML for the Uninitiated
If you’ve found yourself yearning for a document format that makes it easy and flexible to exchange data across the Web, then you should learn about XML, or Extensible Markup Language. . Computer software of all kinds already use XML for data organization and presentation.
Because of the way the XML language is structured, it is possible to exchange data in many different forms. Users find that XML makes data access simpler than is possible with HyperText Markup Language, more commonly known as HTML. Consider that XML programming has the capability to display one web page in either a mobile or regular format, depending on the user. Developers then could make one page instead of two. The ease and efficiency of XML should be becoming more clear.
It isn’t necessary to have extensive prior experience with HTML in order to operate well using XML. The two do go hand-in-hand in many respects, since they are both descendants of SGML, another markup language.
The purpose of a markup language is to organize, categorize, or otherwise label content, and the markup describes the organization. Markup contains the content, which is what you are looking at when you see an XML page rendered.
The need for XML emerged when the limitations of HTML became clear. In HTML, users cannot add new markup elements. With a need for greater flexibility, XML evolved to meet the needs of document and data handling in a web environment.
This is just a short introduction for those who wonder just what the heck XML is. For those who wish to make the most of web development, it’s a great idea to put learning XML on your list of things to do.
