Need to take a value from the csv file and query in a OAF page.

Question

Hello,
I have a requirement to take the list of employee numbers in a csv file and display its corresponding job on the page.
I have created a item 'MessageFileupload' where the user will upload the csv file containing the employee number and a Button 'Display Jobs' which will display the corresponding jobs on the page.
Any idea how to take the values from the csv file and query it?
Regards,
den123.
