How to read a text file with header and data, whose structure keeps changing?

I have a .txt file which is as follows:

Header: Filename 0 Conditions R_FBKRN_target0 Time 3:01:27 PM Date 10/26/10 Feedback_during_trial FB Feedback_after_trial KR

Names:

sec CursorX CursorY FingerX

DATA:

3 23 33 12

2 11 11 23

I need to read the entire file, such that the data from Header: to Names : is in %s %s format, and data after Names: , the respective column headers with their values. Also, while reading, I need to ignore the terms Header: , Name: and DATA
