RegExp去除HTML评论 [英] RegExp to strip HTML comments

问题描述

寻找正则表达式匹配序列并替换（最好是PHP，但无所谓）来改变它（开始和结束只是需要保留的随机文本）。

IN：

  fkdshfks khh fdsfsk 
 <！ -  g1  - > 
< div class ='codetop'> CODE：AutoIt< / div> 
< div class ='geshimain'> 
<！ -  eg1  - > 
< div class =autoitstyle =font-family：monospace;> 
< span class =kw3> msgbox< / span> 
< / div> 
<！ -  gc2  - > 
<！ -  bXNnYm94  - > 
<！ -  egc2  - > 
<！ -  g2  - > 
< / div> 
<！ -  eg2  - > 
 fdsfdskh 
  

到此OUT：

  fkdshfks khh fdsfsk 
< div class ='codetop'> CODE：AutoIt< / div> 
< div class ='geshimain'> 
< div class =autoitstyle =font-family：monospace;> 
< span class =kw3> msgbox< / span> 
< / div> 
< / div>

谢谢。

解决方案

你只是想删除评论？如何

  s /<！ -  [^>]  - > // g 
  

或稍微好一些（由提问者自己提出）：

 <！ - （？*） - > 
  

但请记住，HTML不是常规的，所以使用正则表达式来解析它会导致你进入一个受到伤害的世界，当有人抛出离奇的边缘案例时。

Looking for a regexp sequence of matches and replaces (preferably PHP but doesn't matter) to change this (the start and end is just random text that needs to be preserved).

IN:

fkdshfks khh fdsfsk 
<!--g1-->
<div class='codetop'>CODE: AutoIt</div>
<div class='geshimain'>
    <!--eg1-->
    <div class="autoit" style="font-family:monospace;">
        <span class="kw3">msgbox</span>
    </div>
    <!--gc2-->
    <!--bXNnYm94-->
    <!--egc2-->
    <!--g2-->
</div>
<!--eg2-->

to this OUT:

fkdshfks khh fdsfsk 
<div class='codetop'>CODE: AutoIt</div>
<div class='geshimain'>
    <div class="autoit" style="font-family:monospace;">
        <span class="kw3">msgbox</span>
    </div>
</div>

Thanks.

解决方案

Are you just trying to remove the comments? How about

s/<!--[^>]*-->//g

or the slightly better (suggested by the questioner himself):

<!--(.*?)-->

But remember, HTML is not regular, so using regular expressions to parse it will lead you into a world of hurt when somebody throws bizarre edge cases at it.
