I'm working on an app that needs to extract data from text files output by other
applications. What's needed is relatively simple: look for a line
starting/containing some string, then either copy some following number of lines
or copy one or more "fields" from the line as defined by some pattern or simple
delimiter. This could be done by combining grep and cut commands in a *nix
script file.
It's getting worrisome to think that the "rules" are buried in the code while
the output of these (third-party) apps can change slightly.
So I'd like to find something that lets me create a table of rules (externally),
and a component that I can add to my Delphi app that interprets those rules at
run-time. If any of the data file formats change, then we can update the rules
and distribute just the rule base to users, rather than rolling an entire update
of the software to accomodate these changes.
TIA
