A simple example of xtream

Reprinted from: http://www.ibm.com/developerworks/cn/xml/x-xstream/

 

In this example

The writer class writes the class employee into the file in XML format.

Reader class converts XML into an instance of the employee class.

When xtreamtest reads XML files, each node in XML becomes an attribute.

 

Config. xml
