Deserializing an Object from XML Using Schema

[Veilchen]

Hi,

I need to deserialize an existing object (not generate its code) from a
serialized XML file.
The only information I have about how the deserialization method is an input
XML schema (which can vary) associated with the XML file containing the
serialized object data. Therefore pre-defining it in code using xml
attributes on the serialized class narrows it to only one serialization
method and won't do.
How can I use the schema to deserialize the object?

Thanks,
Sigalit.

How do you reference the object in your .NET code?

I don't understand what you mean when you say that the schema can vary. Do
you mean that the schema for a given type can vary, or that there are
several types you're dealing with?

I meant that the schema can vary.

Yes, but under what circumstances?

I really don't understand what you're asking.

I meant that I am looking for way to deserialize an object from XML using
only a schema which will contain the information about how to deserialize,
without depending on any deserialization information defined in my object.

I guess I'm still being dense here.

You want the schema to be able to change without changing your object? How
will your object hold the changed data? How will it refer to it?

Maybe you should just use XML directly and forget about using strongly-typed
objects. Such objects want to know their shape when they're constructed.

Alternatively, you could use a code generator like XSD.EXE or CodeSmith to
create objects from the schema, then deserialize into the objects. This
might work for you.

Otherwise, I'm not understanding how the schema will change and the object
not change.
