Question

我试图为多行字符串构建一个正则表达式php模式，删除具有sn_published类的div

我已经尝试(?s)<div class="sn_published".*?<\/div>它有效，但不会在div中获得整个内容。它停在第一个结束div。

有什么想法吗？提前谢谢。

  <div class="sn_published">

            <div id="snfwid4" class="sn_published_inner clearfix">
                <script type="text/javascript">

Answer 1

你不能。你应该在这种情况下使用DomDocument。这使你的工作变得更加容易。

您可以在Dom中加载HTML，使用getElementsByTagName方法循环遍历所有Div并过滤您需要的内容。

正则表达式选择div中的所有内容
