I've got character-based invoices from old systems that look roughly
like (but much bigger):
DATE DESC CREDIT DEBIT
01/01/2013 SERVICES $1234.50
01/01/2013 PAYMENT $1000.00
BALANCE $234.50
I don't know exactly how they're formatted, so I'm working from
examples. My initial plan was to hand-code a dumb parser with regular
expressions, but I suspect there's a better way. In particular, it'd be
nice to have some leeway as to exact positions of data, and hopefully
some nice error reporting and recovery abilities.
Can anyone point me towards a parsing technique that would lend itself
to this problem?
Thanks,
Dave
