我想正则取得ID为b的UL里的每一个li里的内容,正则应该怎么写?

/
    .*?(.*?).*?/is  只能匹配到第一个li里的内容

    回复讨论(解决方案)

    $s=<<<html<ul id="a"><li style="display:none">xxx</li><li style="display:block">xxx</li><li>xxx</li></ul><ul id="b"><li style="display:none">xxx</li><li style="display:block">xxx</li><li>xxx</li></ul>html;preg_match('#<ul id="b">(.+)</ul>#is',$s,$m);preg_match_all('#<li[^>]*>(.+)</li>#isU',$m[1],$arr);print_r($arr[1]);
    Copy after login

    不分两次行么?

    能力有限,看其他高手有妙招不。

    不能用jquery吗?
    $('#b')->find('ul')->find('li')就是你想要的内容了。

    (?(?:\s*

    .*?\s*)*)\s*(.*?)\s*  给你个参考,你自己根据需求再修改下
