Print class list attribute in xml

Question

How can I generate an xml file in java, from a class that receives an Arraylist as attribute. I am not able to access the indexes of this Arraylist at the time of passing to the string that will be saved in xml.

I don’t know which lib you’re using to serialize objects in XML, but I usually use Xstream.

In case of serializing a list of products of an object Carrinho which has a list of products:

XStream xstream = new XStream();
xstream.alias("Produtos", List.class);
xstream.toXML(carrinho.getProdutos());
