I just recently had to solve a similar problem. It's not perfect, since
you have to add an "add" method to the target object (I just call it
"addIgnored") which ignores the elements, but it would look like this:
<struct name="ItemAttrribute" class="com.smuts.aws.ItemAttribute">
<collection add-method="addIgnored">
<value style="element" name="Actor" />
</collection>
<value style="element" field="director" name="Director" />
With an extra method in the ItemAttributes class like this:
public void addIgnored( Object o )
{
// Do nothing
}
(just making the collection usage="optional" doesn't work - the jibx
compiler won't compile a collection element that doesn't have some means
of adding it to the parent object, unfortunately).
I found this difficult to determine from the published docs; I added
some samples up on the Wiki, but if anybody's working on revamping the
documentation ;) I hope he'll see fit to include my samples (or similar
ones) in the "official" tutorial.

Subject: [jibx-users] Optional collection
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.
