Hmm. I am so good :-) last night I was working hard to understand the
abstract mapping as I thought it could be a solution.
Hmm. I am so bad :-( I was not able to understand it enought to solve my
problem.
Mocky! Thanks a lot!
Hopefully works. It seems I can try out only on the weekend.
At this moment I do not plan to marshal any time, so duplication it is
not a problem in the near future.

I forgot to mention that this binding is suitable for input only, you'll
get duplicate data in your XML if you marshal your objects out using
this approach.

If you define an abstract mapping for your type "Source" that defines a
choice between either your "spec" structure or your "str" structure,
then you can use that one type as the type to put into your collection.
And that will do what I think you are asking for.
<binding>
<mapping name="source" class="A">
<collection field="sourceList" item-type="Source">
<structure type="Source"/>
</collection>
</mapping>
<mapping class="Source" abstract="true">
<structure choice="true" ordered="false">
<structure name="spec" usage="optional">
<value field="base" style="text"/>
<value name="tag" field="tag" default="spec"
usage="optional"/>
<value name="ev" field="attr" usage="optional"
style="attribute"/>
</structure>
<structure name="str" usage="optional">
<value field="base" style="text"/>
<value name="tag" field="tag" default="str"
usage="optional"/>
<value name="ref" field="attr" usage="optional"
style="attribute"/>
</structure>
</structure>
</mapping>
</binding>
I also put in a new value named "tag" that is optional with a default.
Since this is never actually present in your XML you'll always get the
default which will let you distinguish between the different types.
There may be a better way to accomplish that.

Hi,
I can not deal with the following situation:
I have several 'collections' in my xml document with the same data
structure, so I would like to map them to the same ArrayList and class.
It seems that I would like to make a duplicate conversion. (???; see the
binding defintion at the bottom of the email)
==================================
<source> #ArrayList
#collection_1
<spec ev="ev1">sp_1</spec>
<spec>sp_2</spec>
<str>st_1</str>
<str ref="ref2">st_2</str>
<plasm>plasm</plasm>
</source>
==================================
ArrayList SourceList
SourceList[1]
tag = "spec"
base = "sp_1"
attr = "ev1"
SourceList[2]
tag = "spec"
base = "sp_2"
2.attr = ""
SourceList[3]
tag = "str"
base = "st_1"
attr = ""
etc...
================
I can not change the the structure of the xml file.
In the worst case I can loose the 'tag' information.
I appreciate your help,
Tamas
=============================================
<mapping...
<structure name="source" usage="optional">
<collection name="scpec" field="sourceList" ordered="false"
item-type="org.biohegedus.biodb.bindings.Source"/>
<collection name="str" field="sourceList" ordered="false"
item-type="org.biohegedus.biodb.bindings.Source"/>
</structure>
</mapping>
<mapping name="spec"
class="org.biohegedus.biodb.bindings.Source">
<namespace uri="http://biohegedus.org/biodb/bindings";
default="elements"/>
<value field="base" usage="required" style="text"/>
<value name="ev" field="attr" usage="optional"
style="attribute"/>
</mapping>
<mapping name="str"
class="org.biohegedus.biodb.bindings.Source">
<namespace uri="http://biohegedus.org/biodb/bindings";
default="elements"/>
<value field="base" usage="required" style="text"/>
<value name="ref" field="attr" usage="optional"
style="attribute"/>
</mapping>
