Retreiving data from XML file and writing them in MS access

Hello All,
I am looking to develop an application in VB.net and C#.  I do not have an IT background and I work in construction project management and I would like to know if the idea is feasible.
Here is the problem:

- I have an XML file (exported from MS project: a project plan which contain activity start date, finish date, duration, etc.)
- I require a code that can read specific fields from the XML file (let's say activity names, their start and finish dates, dependencies) and write them in a table in MS access with their attributes (e.g. activity name = prepare foundation, duration = 15 days).
- I will manipulate these data in MS access (e.g. the new duration for "prepare foundation" will become 20 days instead of 15)
- The code should write these changes back in the XML file so I can import it again in MS project with the changes made.

I really appreciare your help in this matter.

Thanks
Mohamad
