How to handle collection of object in apapche digester?

i'm using apache digester-2.0 to convert XML to java beans and it's works fine. But now i've an evolution to do and the structure of the file is a bit more complex. Indeed now , my XML is like that :

<main>
*some properties here*
 <objectCollection>
    <object>
      <id>foo</id>
      <string>bar</string>
    </object>
    <object>
      <id>foo</id>
      <string>bar</string>
    </object>
  </objectCollection>
</main>

So , since now i've handled simple lines like

<title>foo</title>

But i don't find how to handle correctly the collection. Is there some good practice ? i guess i can do a loop on xml objectCollection node, but it seems very weird for me. Isn't a better method ?

Thx
