[Omaha.pm] regex gurus

So, you have this:
 my $condstring="include_1 (f7 ne \'ce\' and f10 ne \'r\' and f1 ne
\'ce\' and f8 ne \'lg\' and f8 ne \'li\' and f8 ne \'lj\' and f8 ne
\'lr\' and f8 ne \'lu\' and f8 ne \'lv\' and f8 ne \'tl\' and f8 ne
\'ta\' and(f4 eq \'e\' or f4 eq \'g\' or f4 eq \'w\')) ";

And you want to break it up so that you get an array something like this:
 @condarr = ["f7", "ne", "\'ce\'", "and", ..., "eq", "\'w\'"];
???

If so, a basic split using "/ /" should do it:
 @condarr = split / /, $condstring;

But, you mentioned grouping the array based on ()s.

  @condarr = [
    include_1,
    [
        f7 ne \'ce\' and f10 ne \'r\' and f1 ne \'ce\' and f8 ne
\'lg\' and f8 ne \'li\' and f8 ne \'lj\' and f8 ne \'lr\' and f8 ne
\'lu\' and f8 ne \'lv\' and f8 ne \'tl\' and f8 ne \'ta\' and,
        f4 eq \'e\' or f4 eq \'g\' or f4 eq \'w\',
    ]
]
(Probably not syntactically correct - done by hand...)

Is something like this closer to what you are looking for?

A split based on the parethesis characters might do it, but you'd have
to make sure the regexp would handle nested parenthesis correctly...
