Hi,
I try do to a < simple > thing :
Knowing If a string like "13" exist in a string like "123"
Or if "37" exist in "12356789"
I tried many solutions, but never found one good so I try to do it with
loops which more difficult but not impossible
I'd like to know if with RegExp it's more simply
No, it's not possible with RegExp. What you want is called the Longest
Common Subsequence. See http://www.ics.uci.edu/~eppstein/161/960229.html
for a description of the algorithm. There are a number of modules in
CPAN http://search.cpan.org/ under "LCS"
http://search.cpan.org/search?query=lcs&mode=module but since I don't
use any, I won't recommend any.
