regex php: find everything in div

Question

I'm trying to find eveything inside a div using regexp. I'm aware that there probably is a smarter way to do this - but I've chosen regexp.

so currently my regexp pattern looks like this:

$gallery_pattern = '/<div class="gallery">([sS]*)</div>/';  

And it does the trick - somewhat.

The problem is if i have two divs after each other - like this.

<div class="gallery">text to extract here</div>
<div class="gallery">text to extract from here as well</div>

I want to extract the information from both divs, but my problem, when testing, is that im not getting the text in between as a result but instead:

"text to extract here </div>  
<div class="gallery">text to extract from here as well"

So to sum up. It skips the first end of the div. and continues on to the next. The text inside the div can contain <, / and linebreaks. just so you know!

Does anyone have a simple solution to this problem? Im still a regexp novice.

You shouldn't be using regex to parse HTML when there's a convenient DOM library:

$str = '
<div class="gallery">text to extract here</div>
<div class="gallery">text to extract from here as well</div>
';

$doc = new DOMDocument();
$doc->loadHTML($str);
$divs = $doc->getElementsByTagName('div');

if ( count($divs ) ) {
    foreach ( $divs as $div ) {
    echo $div->nodeValue . '<br>';
    }
}
