split question

jrsmith has asked for the wisdom of the Perl Monks concerning the following question:

is there any way to retain the character you are splitting by when you do a split()? say i have the string "4sheet1rev11" and i want to split it on each number.. problem is it deletes the number in the process, giving me-

sheet
rev
[download]

when i want-

4
sheet
1
rev
11
[download]

can anyone help me here?

put the delimiter (here: one or more digits) in parentheses, that also returns the delimiters: `my $str = "4sheet1rev11"; my @arr = split(/(\d+)/, $str);` [download] note, that you have an empty string at the beginnig of the array, since your string starts with a digit. cheers sc	[reply] [d/l]

I know you can do it with a regular-expression. I'm not sure if you can with a regular split. `my $s='4sheet1rev11'; while($s=~/([\d]+\|[^\d]+)/gcsi){ print "$1\n"; }` [download] Just saw the other comments. It can be done w/ split. That's what I love about perl... there are always many ways to solve any problem and I'm always learning something new.	[reply] [d/l]
