GumTree provides an useful API to handling parameters or properties in XML format. Assume you want to configure your system using key-value pairs, and make them serialisable, XStream + org.gumtree.core.util.IParameters is your answer.

Say we have three key value paris as shown:
Key |

Retrieving the content is simple:
