content consists of more divs

Question

The problem is when the content consists of more divs, nested divs like this:

 <div class="box" id="customer-login">Content <div class="bl-2">more stuff</div>more contents</div>

Any ideas on how I make my regexp work with nested tags?

Thanks

Don't use regex to parse XML, use DOM. Allow me to recommend this article: http://stackoverflow.com/a/8412989/5290909 — Mariano, Sep 23 '15 at 06:51

Try a parser instead:

require_once "simple_html_dom.php";
$text = 'foo <div id="t1">Content <div>more stuff</div></div> bar <div>even more</div> baz  <div id="t2">yes</div>';
$html = str_get_html($text);
foreach($html->find('div') as $e) {
    if(isset($e->attr['id']) && preg_match('/^t\d++/', $e->attr['id'])) {
        echo $e->outertext . "\n";
    }
}

Output:

<div id="t1">Content <div>more stuff</div></div>
<div id="t2">yes</div>

Download the parser here:http://simplehtmldom.sourceforge.net/

Edit: More for my own amusement I tried to do it in regex. Here's what I came up with:

$text = 'foo <div id="t1">Content <div>more stuff</div></div> bar <div>even more</div>
      baz <div id="t2">yes <div>aaa<div>bbb<div>ccc</div>bbb</div>aaa</div> </div>';
if(preg_match_all('#<div\s+id="t\d+">[^<>]*(<div[^>]*>(?:[^<>]*|(?1))*</div>)[^<>]*</div>#si', $text, $matches)) {
    print_r($matches[0]);
}
