Im trying to parse a file which contains some random text.
How can i match a case which seperates "garbage" (anything but digit/letter) char??
for e,g: 25.5.5 will produce . (the 2nd dot, because 25.5 is a number (rational))
----3.82 will produce --- (because -3.82 is a rational)
but it wont fit the cases i mentioned above.
