如何用正则解析这样的字符串？

形如：

<code>$str='<p>hhhhhhhhhhhhh</p>'

$str='<h1>jjjjjjjjjjjjjjjj</h1>'

</code>

想要得到p或者h1之间的内容,怎么写？

回复内容：

形如：

<code>$str='<p>hhhhhhhhhhhhh</p>'

$str='<h1>jjjjjjjjjjjjjjjj</h1>'

</code>

想要得到p或者h1之间的内容,怎么写？

<code><?php $reg = '/<([a-z0-9]+)>([\s\S]+?)/';

$str='<p>hhhhhhhhhhhhh</p>';
preg_match($reg, $str, $result);
var_dump($result);

$str='<h1>jjjjjjjjjjjjjjjj</h1>';
preg_match($reg, $str, $result);
var_dump($result);
</code>

运行结果:

<code>array(3) {
  [0]=>
  string(20) "<p>hhhhhhhhhhhhh</p>"
  [1]=>
  string(1) "p"
  [2]=>
  string(13) "hhhhhhhhhhhhh"
}
array(3) {
  [0]=>
  string(25) "<h1>jjjjjjjjjjjjjjjj</h1>"
  [1]=>
  string(2) "h1"
  [2]=>
  string(16) "jjjjjjjjjjjjjjjj"
}
</code>

$reg='#(.+?)#s'
