XML stands for eXtensible Markup Language. It is extensible, because it does not use a predefined set of tags for identifying structural components; instead, it provides a mechanism for defining such sets of tags. The main purpose of the language is to share the data. Unlike in HTML, there is no predefined set of tags in XML and tags specify meaning, rather than the presentation.
XML syntax refers to the rules that determine how an XML application can be written. The XML syntax is very straight forward, and this makes XML very easy to learn.
* Simplicity - XML documents are ordinary text files that can be created and edited with any text editor.
* Vendor independence
* Platform independence
* Extensive infrastructure
* Disadvantages of using XML:
* Verbose and cumbersome syntax
* Highly inefficient storage
