Stripping numbers from a string
|
|

| This should be an easy one for you seasoned perl developers.
I've got a string that may or may not begin with one or more numbers.
For example, it might be "Smith, John" or it might be "83Smith, John".
I only want the text portion of the string. How do I make sure that
regardless of which of the above is passed to me, I only get "Smith,
John"?
Thank you.

my $string = '83Smith, John';
$string =~ s/\d//g;

Thanks. I can't believe I didn't think of that.

actually, i think the below is faster:
$string =~ tr/0-9//d;

Or more safely:
$string =~ s/^\d+//;
Who knows when you'll run into "83Smith 4th, John"...

It probably is, but both do not do what the verbal description asks for:
Deleting "one or more numbers" that might precede a name. Reading
"numbers" as "digits", that would be
s/^[0-9]+//;
Reading "numbers" as "numbers", one would have to ask about separators.

excellent point. when i read that the OP only wanted the text portion
of the string, i (possibly erroneously) designed a simple regex to
delete all digits from the string, regardless of position. i should
have looked more closely at the OP's first paragraph.
