Java: печать данных xml с использованием библиотеки классов XStream

Question

Как печатать XML на терминале экрана с помощью библиотеки классов XStream?

мне нужно напечатать

System.out.println(recordXML.read()); 

Но он возвращает:

<list><registrosarraylist02xml.Pessoas><ID>1</ID><nome>Regis</nome><idade>25</idade></registrosarraylist02xml.Pessoas><registrosarraylist02xml.Pessoas><ID>2</ID><nome>Rose</nome><idade>32</idade></registrosarraylist02xml.Pessoas><registrosarraylist02xml.Pessoas><ID>3</ID><nome>david</nome><idade>10</idade></registrosarraylist02xml.Pessoas></list> 

Я хочу, чтобы напечатать что-то похожее на:

System.out.println(p.ID + " - " + p.name + " - " + p.age); 

ID - имя - возраст 1 - Регис - 25

2 - Роза - 32

3 - Давид - 10

2 - Rose - 32 
3 - david - 10
