Html; preg_match ('#

(. +)

# Is ', $ s, $ m); preg_match_all ('# ] *> (. +)# IsU ', $ m [1], $ arr); print_r ($ arr [1]);

Can't I use jquery?
$ ('# B')-> find ('Ul ')-> find ('Lil') is what you want.

(? <=

(? : \ S * .*? <\/Li> \ s *) \ s * (.*?) <\/Li> \ s * to give you a reference. you can modify it as needed.
