$str = '

内容A

内容B

'
请问一下，用正则分别取出内容A 跟内容B 正则要怎样写呢？
注：内容A，内容B 中间会有换行符。

回复讨论(解决方案)

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>

$str = '

内容A

内容B

';
preg_match_all('/(.*?)<\/div>/i',$str,$match);
echo $match[2][0];//内容A
echo $match[2][1];//内容B

默默收藏

preg_match_all('/

(.*?)<\/div>/is',$subject,$match);
var_dump($match);

preg_match_all('/

(.*?)<\/div>/is',$subject,$match);
var_dump($match);

好像有点问题。不是很准。

array(3) {  [0]=>  array(2) {    [0]=>    string(86) "<div class="superStar" id="test_0"> 				you dead!				<div class="show">hello</div>"    [1]=>    string(80) "<div class="superStar" id="test_1">				shit!				<div class="contne">hi</div>"  }  [1]=>  array(2) {    [0]=>    string(12) " id="test_0""    [1]=>    string(12) " id="test_1""  }  [2]=>  array(2) {    [0]=>    string(45) " 				you dead!				<div class="show">hello"    [1]=>    string(39) "				shit!				<div class="contne">hi"  }}

少了〈/div〉

preg_match_all('/<div class=\"superStar\"(.*?)>(\s*(?:<div.*<\/div>\s*)*)<\/div>/us',$subject,$match);echo $match[0][0];echo '<hr />';echo $match[0][1];

Copy after login

<?php$subject = '<div class="superStar" id="test_0">                 you dead!                <div class="show">hello</div>                <span>james</span>            </div>            <div class="superStar" id="test_1">                shit!                <div class="contne">hi</div>                <ul><li>list</li></ul>            </div>';preg_match_all('/<div[^>]+>(([^<]*|<(?!div)|(?R))+)<\/div>/us',$subject,$match);echo $match[0][0];echo '<hr />';echo $match[0][1];

Copy after login

<?php$subject = '<div class="superStar" id="test_0">                 you dead!                <div class="show">hello</div>                <span>james</span>            </div>            <div class="superStar" id="test_1">                shit!                <div class="contne">hi</div>                <ul><li>list</li></ul>            </div>';preg_match_all('/<div[^>]+>(([^<]*|<(?!div)|(?R))+)<\/div>/us',$subject,$match);echo $match[0][0];echo '<hr />';echo $match[0][1];
