Abstract:
XML stands for eXtensible Markup Language. XML is used to aid the exchange of data. The language makes it possible to define data in a structured way. XML tags are not predefined like HTML. XML lets you create your own unique tags that are meaningful for your data, hence the use of the term 'extensible.'
