一次测试中有很多段落。
<div class="text">...</div>
<div class="content">...</div>
<div class="aa bb">...</div>
<div class="aa cc">...</div>
<div class="aa dd">...</div>
<div class="aa ee">...</div>
<div class="aa ff">...</div>
...// more type of class="aa .*"
我想删除所有div class="aa"
,但div class="aa dd"
除外,如何完成这项工作?谢谢。
$html = preg_replace('/<div(.*?)class="aa(.*?)">([\s\S]*?)<\/div>/', '', $html);
// this will remove all the div include class 'aa', but I need remain class 'aa dd'
答案 0 :(得分:2)
echo preg_replace('~<div class="aa (?!dd).+?">.+?</div>~', "", $html);
