I managed to create three almost identical converters for the three
ArrayList<String> elements of my Java structure and I can both read and
write XML in the desired format.
I was unable to see how to get the CollectionConverter or
NamedCollectionConverter to fit in. I don't have distinct types for the
three lists and the examples I saw assumed a distinct type for the
collection.
I was trying to use the annotation approach because that seemed to be
the only way to be specific about which of the ArrayLists I was
referring to. It was not clear how to proceed and trial and error was
not effective for me.
What I would really like is an annotation or combination of annotations
that combines a top level alias with an implicit alias, something like
@XStreamCollection("movies", "title")
ArrayList<String> movies;
@XStreamCollection("plays", "title")
ArrayList<String> plays;
etc., producing
...
<movies>
<title>Title 1</title>
<title>Title 2</title>
</movies>
<plays>
<title>Title 1</title>
<title>Title 2</title>
</plays>
It seems to me that simple collections or maps are somewhat special. If
it were more complex than a simple collection, a person would typically
want to develop a class but for just a list of items a special class is
much less compelling.

I'm still struggling. Where can I find ParameterizedConverterTest?

One additional aspect: I have three instances of the ArrayList<String>
in my object, each with different inner element names.
Register a local converter for each instance.
Also have a look at the parallel thread with the CollectionConverter and
@XStreamConverter annotation.
Cheers,

I'm trying to handle an ArrayList<String> to achieve XML like the

The examples Ive seen let me name the outer <entries> element or
eliminate the outer element and name the inner elements. Is there a way
to
achieve both? I'm using annotations but I'm not tied to them.
Register a local converter of type NamedCollectionConverter for the
field. This is also possible with annotations, but a bit tedious. You may
have a look at the ParameterizedConverterTest for an example.
