Hello,I was a bit surprised to see that nobody has still answered to my problem. I thought that exchanging objects between databases is one of the main applications for XML files. Maybe this is only theory and one day everybody will say : "Of course theoretically this was one of the main applications, but in practice it could not be managed to adapt the XML schema to changes of the database schema(s). Often it was too complex to do this manually, and there were no tools for managing this automatically." This idea I got when I read the articles of mojojojo (Tools for schemas).But nevertheless I am looking forward to posts from readers having some experiences in exporting and importing database tables with an XML based exchange format (or some other format).
