hi joshua,
sorry for the confusion.
i didn't actually try to run your example. for one thing
i don't have a copy of your model code. the binding
fragments that i used were just a means for me to
illustrate what i wanted to communicate/convey.
as i'm sure you know, jibx currently (beta3c, which is what
i normally use) supports java.util.ArrayList best.
is your authors field an ArrayList? if not you would have
to provide additional information on the collection binding
such as iter-method.
as far as i know what i'm describing should work in
principle using beta 3c. sounds like you're almost there.
thanks, eitan

Eitan, when I tried both of your samples below, I got this error from
the binding compiler:
org.jibx.runtime.JiBXException: Unknown collection type with no add or
store method defined at tag "collection"(line 5, col 34, in
sample_binding.xml)
What version of jibx are you running? (I'm running beta-3c) If the
(still not officially released) alpha-4.0 code supports this feature,
this will be a welcome one, since it's much more straightforward than
the hack I've been using to get around this.

Subject: Re: [jibx-users] Optional collection
you don't have to resort to using the 'optional' keyword to omit part
of the xml while unmarshalling.
the jibx documentation shows an example binding where a set of xml
'instructions' are skipped
(in the structured mapping section of the tutorial).
a collection or a structure that has no corresponding field on your
java class can be mapped
like this:
<structure name="itemAttributes" field="_itemAttributes">
<collection name="actors" />
<value name="AudienceRating" field="rating" />
...
</structure>
the lack of a corresponding "field" attribute on the collection will
cause jibx to skip that xml.
in your case there is no wrapping "actors" element around each actor
child element. so
the binding would have to be slightly different.
<structure name="itemAttributes" field="_itemAttributes">
<collection item-type="Actor" />
<value name="AudienceRating" field="rating" />
...
</structure>

I have an xml file that has more data than I want to map to my
objects.
I can skip singly occuring elements with a structure with just a name
that is marked optional. However, how can I handle unbounded elements
that I don't want to map?
The Aws wsdl has lots of these.
http://aws-beta.amazon.com/AWSAlexa/AWSAlexa.wsdl
For example, say I get an item like the one below back and I don't
want the actor element in the itemattributes section. I could put
three structures in, but then as soon as I get a movie with 4 actors
listed, it will break.
