正则表达式：从 --- 评论部分 --- 中删除单词

Question

我在博客中有很多以https://mywebsite.com。我想从特定评论部分删除这些链接（但在 /story1.html、/story2.html 等之前）

<!-- FLAGS1 --> <div class="cotarerField"> <div align="right">

<a href="https://mywebsite.com/story1.html"><img src="index_files/flag_lang_ro.jpg" title="ro" alt="ro" width="28" height="19" /></a>&nbsp;

Answer 1

• Ctrl+H
• 找什么：(?:\A[\s\S]*<!-- FLAGS1 -->|\G)(?:(?!<!-- FLAGS1 -->)[\s\S])+?\Khttps://mywebsite\.com/(?=[\s\S]*<!-- FLAGS1 -->)
• 用。。。来代替：LEAVE EMPTY
• 检查环绕
• 检查正则表达式
• Replace all

解释：

(?:                         # non capture group
  \A                        # beginning of file
  [\s\S]*                   # 0 or more any character
  <!-- FLAGS1 -->           # literally
 |                          # OR
  \G                        # restart from last match position
)                           # end group
(?:                         # non capture group (Tempered Greedy Token)
  (?!<!-- FLAGS1 -->)       # negative lookahead, make sure we haven't <!-- FLAGS1 -->
  [\s\S]                    # any character
)+?                         # end group, appears 1 or more times, not greedy
\K                          # forget all we have seen until this position
https://mywebsite\.com/     # text to be removed
(?=[\s\S]*<!-- FLAGS1 -->)  # positive lookahead, make sure we have <!-- FLAGS1 -->  after

鉴于：

<a href="https://mywebsite.com/ru/story10.html"><img src="index_files/flag_lang_ru.jpg" width="28" height="19" title="ru" alt="ru" /></a>

<!-- FLAGS1 --> <div class="cotarerField"> <div align="right">

<!-- FLAGS1 -->

<a href="https://mywebsite.com/ru/story10.html"><img src="index_files/flag_lang_ru.jpg" width="28" height="19" title="ru" alt="ru" /></a>

给定示例的结果：
