Issue has been solved.We need to do the following things..
- A class "XXX-Data-Table", which contains two properties: Country, City.
- A class "XXX-Data-NewDataSet", which contains one Page List property of the class "XXX-Data-Table".
Then, in your parse XML, you want to populate a page of the class "XXX-Data-NewDataSet" (this page will store the results of the parsing). The element Table of your Parse XML should be mapped to the Page List property that you have defined at "XXX-Data-NewDataSet". The other two properties should be mapped to the properties you have defined at "XXX-Data-Table".
