Hi, i want to modify two fields in a xml file which should select xml file from solution explorer. Also the two fields should display same "number" which is selected from the .CSV file.  Finally the xml should be placed to the particular file.

 Only two fields must change not all.
 
Finally if i want 20 feeds it should select 20 values from .csv file and should generate 20 feeds(that many xml files)
 
So please give me the code in c# format.
