Use strpos to find first tag position. Then find ending tag also with strpos. I mean - if u know from where to what you are looking for and they are unique.. so what matter in preg_* functions?
So i guess something like this will work fine (I make code clear as possible for understanding my idea in step-by-step actions):
$tag_begin = "<!-- icon and title -->"; $tag_end = "<!-- message -->"; $begin = strpos($tag_begin,$text)+strlen($tag_begin); $end = strpos($tag_end,$text); $result = substr($begin,$end, $text);
Also u can do exactly the same if u want find and store all structures between opening <!-- (.*) --> and closing <!-- / (.*) -->. Only change u must do - first find with preg_match all opening structures names. For example:
$result_cnt = preg_match_all('#<!-- [^/].*-->#', $text , $openings);
// Output for your example HTML is:
$openings =
array (
0 =>
array (
0 => '<!-- icon and title -->',
1 => '<!-- message -->',
),
)
After that one-loop for $openings and find with code above all needed. just adding to openings closing "/" chacter in right place.
