These are the main benefits of using XML.
Simplicity : Very easy to read and understand the information coded in XML.
Openness : It is a W3C standard, endorsed by software industry market leaders.
Extensibility : It is extensible because it has no fixed set of tags. You can define them as you need.
Self-descriptive : XML documents do not need special schema set-up like traditional databases to store data. XML documents can be stored without such definitions, because they contain metadata in the form of tags and attributes.
Scalable : XML is not in binary format so you can create and edit files with anything and it is also easy to debug.
Fast access : XML documents are arranged in hierarchical form so it is comparatively faster.
