Stuck with php regular expression

So I have been trying to figure out regex to capture multiple sections of my data but, seems I've been failing since last two days now...:(

Please help Let's say following is my data :

<div class="tabs_container">
<ul class="tabs">
    ##BEGINLOOP##gAs##
        <li><a href="#">##title##</a></li>
    ##ENDLOOP##
</ul>
    ##BEGINLOOP##LI##
    <div class="tabs_content">##title## is ##content##</div>
    ##ENDLOOP##
</div>

and i want to capture following group:

  1. The text before ##BEGINLOOP##
  2. The text after ##BEGINLOOP## and before ##(gAs in first and LI in second)
  3. Text After ##ENDLOOP##

I have been trying various regex combination but nothing worked for giving me the exact solution. This was my last try 

'/(?:##BEGINLOOP##)([a-z|A-Z]*)##(.+?)(?=##ENDLOOP##)(?:##ENDLOOP##)/s'

I am using PHP preg_match_all function

Please help ?

The regex is close to be right. Just a few notes:

[a-z|A-Z] does not mean what you think it means. It means accept all chars from a to z, and the char |, and all chars from A to Z. You want [a-zA-Z].

(?=##ENDLOOP##) means that the next group matches only if preceded by ##ENDLOOP##, so ##ENDLOOP## will match only if preceded by ##ENDLOOP##. You may want to remove (?=##ENDLOOP##).

This works:

'/(?:##BEGINLOOP##)([a-zA-Z]*)##(.+?)(?:##ENDLOOP##)/s'

Try it here: http://3v4l.org/aCvvY

If you also want to also capture the parts outside of ##BEGINLOOP##...##ENDLOOP##, for the whole document, preg_split does the work:

$parts = preg_split('/(?:##BEGINLOOP##)([a-zA-Z]*)##(.+?)(?:##ENDLOOP##)/s', $subject, -1, PREG_SPLIT_DELIM_CAPTURE);

try:

preg_match('@(.*?)##BEGINLOOP##(.*?)##(.*?)##ENDLOOP##(.*?)@s', $data, $matches);

var_dump($matches);
