Converting XML to DataSet and back?

Question

Programming

There is XML from which I then create a DataSet and bind it to the DataGridView.
1) If I want to convert the DataSet to XML, will the XML get my original structure from which I formed the DataSet?
2When I made some changes through the DataGridView (Added rows, deleted rows, etc in the dataset) and want to convert the DataSet back to XML, will I get my original XML structure?

Answer 1

And what for to transform if it is possible to use XmlDataSource?
