Multiple elements with the same name with SimpleXML and Java

Question

I'm trying to use SimpleXML to parse an XML document (an ItemLookupResponse for a book from the Amazon Product Advertising API) which contains the following element:

<ItemAttributes>
  <Author>Shane Conder</Author>
  <Author>Lauren Darcey</Author>
  <Manufacturer>Pearson Educacion</Manufacturer>
  <ProductGroup>Book</ProductGroup>
  <Title>Android Wireless Application Development: Barnes & Noble Special Edition</Title>
</ItemAttributes>

My problem is that I don't know how to deal with the multiple possible Author elements.

Here's what I have right now for the corresponding POJO (Plain Old Java Object), keeping in mind that it's not handling the case of multiple Authors:

@Element
public class ItemAttributes {
    @Element
    public String Author;

    @Element
    public String Manufacturer;

    @Element
    public String Title;
}

(I don't care about the ProductGroup, so it's not in the class -- I'm just setting SimpleXML's strict mode to off to allow for that.)

I couldn't find an example in the documentation that corresponded with such a case. Using an ElementList with (inline=true) seemed along the right lines, but I didn't see how to do it for String (as opposed to a separate Author class, which I have no need for and don't see how it would even work).

Here's a similar question and answer, but for PHP: php - simpleXML how to access a specific element with the same name as others? I don't know what the Java equivalent would be to the accepted answer.

Thanks in advance.

N.B, this is just from reading the docs (the only question is if it should be name="Author" or entry="Author"):

@Element
public class ItemAttributes {
    @Element(inline=true, type=String.class, name="Author")
    public List<String> authors;
...
}
