[Simple-support] How to deserialize an heterogeneous sequence of elements

[RaphaelJ <rap...@gm...>]

Hello,

I have an XML file that looks like this :

/------------------- sample-script.xml -------------------------\

<script>
	<copy srcDir="src" destDir="dest" filePattern="*.dep" />
	<cleanDir dir="log" />
        <!-- Other commands .... -->
</script>

\-------------------------- END -------------------------------/


I want to parse the sequence of commands, each type of command transforming
into a different class.
I would like to avoid the use of "class='foo.Bar'" attributes.


Here are 3 classes :

/------------------- Script.java ------------------------------\

@Root(name="script")
public class Script {
	@ElementList(inline=true)
	private List<ICommand> commands;
}

\-------------------------- END -----------------------------/


/--------------- CommandCopy.java -------------------------\

@Root(name="copy") 
public class CommandCopy implements ICommand {

	@Attribute
	private String srcDir;

	@Attribute
	private String destDir;

	@Attribute(required=false)
	private String fileFilter = "*.*";
}

\------------------------ END ---------------------------------/


/-------------- CommandCleanDir.java -------------------------\

@Root(name="cleanDir") 
public class CommandCleanDir implements ICommand {

	// -- Attributes
	@Attribute
	private String dir;
}

\------------------------ END ---------------------------------/

All those classes are in the same package.
When I try parse this, I get the following error :
org.simpleframework.xml.core.ElementException: Element 'copy' does not have
a match in class fr.whatever.Script at line -1

I think that Simple-XML could guess the class I want to instantiate, based
on the @Root(name="something") annotation of the class. Should I register
all the possible classes somewhere ? Or does simùple-XML finds out all
annotated classes on his own ?

Is there some way to achieve what I want with Simple-XML ?

Thanks in advance for your help.
Raphael
