Can I process a file with multiple sets of data?

I have a CSV file from a vendor that I need to process that has multiple sets of data--not multiple schemas, but entirely different sets. Here is an example:

** Message
** Timestamp
Data Set 1
Value 1, Value 2, Value 3, Value 4, Value 5
Data, Data,,Data,
Data, Data, Data,,Data

** Message
** Timestamp
Data Set 2
Value 1, Value 2, Value 3
Data,,
Data,Data,Data

** Message
** Timestamp
Data Set 3
Value 1, Value 2, Value 3, Value 4
Data, Data, Data, Data
Data,,Data,

I need to retrieve the data from the second set. I don't know how to have Data Services skip the first set and skip the top three rows of file information before processing the file. The record count for each set varies, of course, so I can't set a row to start reading the file. Can this be done?
