【中文标题】正则表达式选择 div 中的所有内容【英文标题】：Regex to select all the content within the div 【发布时间】：2017-12-27 17:51:18 【问题描述】：我正在尝试为多行字符串构建正则表达式 php 模式，以删除具有 sn_published 类的 div
我已经尝试过(?s)<div class="sn_published".*?<\/div>，它可以工作，但无法获得 div 中的全部内容。它在第一个结束 div 处停止。
有什么想法吗？提前致谢。
<div class="sn_published">
<div id="snfwid4" class="sn_published_inner clearfix">
<script type="text/javascript">

【问题讨论】：
你的预期输出是什么？ 在另一个问题上见this answer。 存在 DOM 解析器时不要使用正则表达式解析 HTML 你试过 DOMDocument 吗？ 我很少会放弃发布指向 the best answer on Stack Overflow ever 的链接的机会 - 谢谢！ 【参考方案1】：你不能。对于这种情况，您应该使用 DomDocument。这会让你的工作轻松很多。
您可以在 Dom 中加载 HTML，使用 getElementsByTagName 方法遍历所有 Div 并过滤您需要的内容。
