I am unable to use "split" with pattern matching to remove alpha characters
from a string and will appreciate a pointer on what I'm doing wrong. (Have
looked in "Learning Perl" and "Programming Perl" but can't spot my error.)
The detail:
"$stat" is a string that has alpha and numeric data in it.
I want to remove all of the alpha and put the numeric data into an array.
The first attempt:
my @nums = split(/a-zA-Z/,$stat); # removes all data from the string
The second attempt:
my @nums = split(/a-z/,$stat); # removes all data from the string
>From reading, my understanding of "split": Discards all data that matches
the pattern and returns a set of list values for the unmatched data. ("my
understanding" may be the problem)
This pattern works - removes all blanks (white space) but leaves alpha and
numbers which of course isn't what I want
my @nums = split(/ +/,$stat); # removes all blanks
