I am looking for an appropriate regular expression.
After parsing a csv file, commas are missing within the strings:
A B 1234 a,b -> A B 1234 a b
A B 1234 c,e -> A B 1234 c e
Not knowing how to avoid the problem in the first place, I thought to fix the problem afterwards. I tried to define a regex, which should find matches within the parsed strings and to substitute them like this:
$id =~ s/[a-z] [a-z]/[a-z],[a-z]/;
But this doesn't work!
Has anybody any idea how to solve this problem?
