XStream - Convert XMl to Java & Vice Versa

XStream is a simple library to serialize objects to XML and back again.

XStream xstream = new XStream();

Person joe = new Person("Joe", "Walnes");

String xml = xstream.toXML(joe)

The resulting XML looks like this:

<code>

<person>

<firstname>Joe</firstname>

<lastname>Walnes</lastname>

<phone>

<code>123</code>

<number>1234-456</number>

</phone>

<fax>

<code>123</code>

<number>9999-999</number>

</fax>
</person></code>

Deserializing an object back from XML

Person newJoe = (Person)xstream.fromXML(xml);
