$str = '
你要得到的事内容A和内容B呢,还是 id="test_0"的text和 id="test_1"的内容呢?
内容A 与 内容B
跟ID无关。不是JS。是PHP取数据。
$subject = '<div class="superStar" id="test_0"> you dead! <div class="show">hello</div> <span>james</span> </div> <div class="superStar" id="test_1"> shit! <div class="contne">hi</div> <ul><li>list</li></ul> </div>';$pattern = '/这里正则如何写/';preg_match($pattern, $subject, $matches);print_r($matches);$pattern_1 = '/这里正则如何写/';preg_match($pattern_1, $subject, $matches);print_r($matches);分别取到结果如下:数据一:you dead!<div class="show">hello</div><span>james</span>数据二:shit!<div class="contne">hi</div><ul><li>list</li></ul>

少了〈/div〉
