[Boost-users] regular expression on table data

Hello all, I have a follow table: OPERATING REVENUES: publishing $ 42,419 $ 44,754 $ 46,203 collegiate marketing and production services 97 ASSOCIATION MANAGEMENT SERVICES 16 wireless 8,883 8,129 7,507 51,302 52,883 53,823 All I know is that OPERATING REVENUES: will be always there, question is how to write a regular expression to capture the total (which is 51,302 here) There might be more/less than four rows in the table. Would really appreciated if anyone has good suggestion on this. /Winson
