XML and Java work very well together.

1. 
   
   Portability – Java is a platform independent development language. XML is an architecture and language independent data format. Both Java and XML do not care about the platform.
   
   


2. 
   
   Extensive development support – There is good API support in Java for XML.
   
   

People are using XML for conducting business-to-business transactions and a standard way for different computers to communicate with each other.
