Object oriented design question

I need to create a class which is building up an XML config file based on another objects.

There are 3 various objects. The building algorithm is very similar for all objects,but not same.

I was thinking of using a base class with an abstract method and then just create a derived classes with where I'd override the abstract method.

But the problem is those 3 object doesn't have a common interface or base class. Those objects are third party components. I can't refactor them. So there isn't any common contract for all objects.

Is there any convenient solution for this situation ? Maybe some design pattern I don't know about ?

For simplicity you could also use a datatable class. These can read and write xml files.

You could define a XMLSerializable abstract class and then use the Adapter pattern to adapt these third party components into XMLSerializable objects

you can create your 3 custom class extending them respectively [I am not sure about C#], and implement a common contract.
