I've been trying to design this regex but for the life of me I could not get it to not match if */ was hit before the special word.
我一直在尝试设计这个regex,但是对于我来说,如果*/在这个特殊的词之前被击中,我就无法让它不匹配。
I'm trying to match a whole multi line comment only if it contains a special word. I tried negative lookaheads/behinds but I could not figure out how to do it properly.
我试图匹配一个完整的多行注释,只有当它包含一个特殊的词。我试了一些消极的想法,但是我不知道怎么做才好。
This is what I have so far: (?s)(/\*.+?special.+?\*/)
这是我迄今为止:(?)(/ \ *。+特别。+ ? \ * /)
Am I close or horribly off base? I tried including (?!\*/)
unsuccessfully.
我离得近还是离得太远?我尝试过包括(?!\*/)但没有成功。

Edit: I had some redundant parts to the regex I removed.
编辑:我删除了regex的一些多余部分。

You were not totally off base:
你不是完全错了:
/\* # match /*
(?:(?!\*/)[\s\S])+? # match anything lazily, do not overrun */
special # match special
[\s\S]+? # match anything lazily afterwards
\*/ # match the closing */
The technique is called a tempered greedy token, see a demo on regex101.com (mind the modifiers, e.g. x
for verbose mode !).
该技术被称为调和贪婪令牌,请参阅regex101.com上的演示(注意修饰符,例如x表示详细模式!)
You might want to try another approach tough: analyze your document, grep the comments (using eg
BeautifulSoup
) and run string functions over them (
if "special" in comment...
).
