    If your HTML is not well formed, you can still use stuff like DOMDocument, e.g.:

    $d = new DOMDocument;
$d->loadHTML($htmlstring);

$x = new DomXPath($d);

foreach ($x->query('//div[@id="mainContent"]') as $node) {
    echo $node->nodeValue;
}

    Alternatively, just prefix the HTML with <!DOCTYPE html> so that you can use getElementById as per normal.
