PHP:正则表达式匹配短语不包含特定单词

Question

我已经厌倦了四处寻找足够近的例子,时间可以获得一些快速的帮助!这是我的代码:

preg_match_all( '#<li.*?>.*?</li>#s', $card_html, $activity );

我想修改它以便<li.*?>排除这个词Unplayed.(这个词出现在之后.*?和之前>.

            <li class="Unplayed"></li>

            <li class="Unplayed"></li>

谢谢.

Answer 1

试试这个.前瞻确保<li>标记的其余部分不包含Unplayed.

preg_match_all( '#<li(?=(.(?!Unplayed))*?>).*?>(.(?!Unplayed))*?</li>#s', $card_html, $activity ); 

编辑:我无法从您的示例中看出来,但听起来像未播放的内容可以在<li>的开始标记内外发生.
