I have an xml file that my application downloads on a periodic basis. I also
have a dataset based on this that is used in the application. At present,
the application takes the new downloaded xml, creates a data set from that
and merges it with one in use. The ultimate goal is to have the update of
the primary data set trigger change events based on only data that has
changed (updates, additions, or deletions).
I am thinking that I need to generate a diffgram based on the current data
and the newly downloaded data and then apply that to the current dataset. Is
this the propper approach, and what is the best way to do this. I am seeing
some postings regarding an XMLDiffPath tool, but they are several yeares
old. How is this done now?
TIA
