Need Help??

in reply to Match integer or floating point numbers, then parse triplets

Maybe you want to use a CSV parser instead? Text::CSV_XS?

Also, (.)+ does not do what you seem to think it does. Maybe (.+) does more of what you want?

$intOrFloat = qr/^[+-]?\ *(\d+(\.\d*)?|\.\d+)([eE][+-]?\d+)?$/;
[download]

metaperl:
Also note that the definition of $intOrFloat given in the OP requires that the integer or float be the only thing in the string (i.e., it must start at the start ^ and end at the $ end), and the example string given in the OP
$_ = "0:20,1.00,g,1.00;65,4.00,g,4.00";
and the pattern used to match it
/0:(.)+,$intOrFloat/
both have other stuff at the start.

Update: metaperl: Good luck with your homework assignment.
