不要使用正则表达式，使用 DOM 解析器，如 DOMDocument 或 SimpleXMLElement。

$dom = new DOMDocument();
$dom->loadHTML($yourHTML);

$finder = new DOMXPath($dom);

//Get all lists:
$lists = $finder->query('//ul');

// get all lists immediately AFTER h3's
$listsAfterHeader = $finder->query('//h3/following-sibling::ul[position()=1]');
