How about using (string-trim " " " 43 76 87 33 89 ") first and then doing split? See http://cl-cookbook.sourceforge.net/strings.html#trim Noldus

I don't think there is (unless you want the initial space to be a part of the first string like " 43"). The easiest solution would be to call something like REMOVE-IF or DELETE-IF directly afterwards.
Cheers, Edi.

I want to parse strings of space-separated integers, and split is perfect except when I have vertical aligned integers. In such cases I've got one or more spaces at beginning of string, and the resulting list has a void string as 1st element:
CL-USER> (cl-ppcre:split "\s+" " 43 76 87 33 89 ")
("" "43" "76" "87" "33" "89")
Is there an option to avoid such initial void string?
Thanks.
