I need to know How I can achieve this goal by classes :

we have two different applications in the company (App1 , App2)

Appl can export xml with know items ( ID , Name)

we need app2 to import this data but App2 display different items (CarID, CarName) and this items defined like this with the mapping info

<CarID>
<Mapping name="ID"/>
</CarID>
<CarNAme>
 <Mapping name="Name"/>
</CarNAme>"

How I can achieve this as classes or ARCHITECTURE , i will develop this with c# I need one interface because we may support different type of files not just xml
