Subject: Idiomatic way for collecting elements using REXML?

I'm writing some REST-ian code to talk to the Amazon Web Services
since there are some bugs in SOAP4R (which I'll explain in a future
mail).

While manually parsing the XML that is returned from Amazon's REST
interface, I wound up writing the following code:

item.details = []
doc.elements.each('ItemLookupResponse/Items/Item') do |item|
  # construct an item_detail
  item_details << item_detail
end

This doesn't *feel* right. I wanted to use collect() but it's not
implemented in REXML. Is there a more Ruby-esque approach to gathering
some objects into an array while parsing XML?

Thanks
