问题与RegEx Lookaround包含新行 [英] Issue with RegEx Lookaround where new lines are included

问题描述

澄清，我正在使用Sublime文本。看来问题实际上是多线问题。谢谢大家的反馈意见！

好的，我试图分析类似于这样的文本块：

<$
>私人小组NAV_VE124_Click（）
'在描述字段中打开图片
调用ShowPic（Me.NAV_VE124.Description）
End Sub

和正则表达式模式（？<= Private Sub）（（。*？）（ ？= _ Click））

似乎可以找到 NAV_VE124

$ b

，但由于某些原因（？<= \'）（（。*？）（？= End））

不会产生任何结果...

任何想法都将不胜感激。 b
$ b

另外，我想结合这两个搜索，所以我只抓住'如果其他条件允许，所以任何想法如何做到这一点也将是惊人的

解决方案

 （？< = \'）（（。| \s ）*（？= End））
  

lem是多行...不知道你使用什么样的正则表达式工具，只是做一个（。| \s）*来匹配任何东西，包括换行符。如果\s不起作用，请找出与您的工具的换行符匹配的内容。

Edit: Clarification, I am using Sublime text. It appears the problem was in fact the multiline issue. Thank you all for your feedback!

Okay so I'm trying to analyze text blocks similar to this:

Private Sub NAV_VE124_Click()
    'Open the picture in its description field
    Call ShowPic(Me.NAV_VE124.Description)
End Sub 

and the regex pattern (?<=Private Sub )((.*?)(?=_Click))

seems to work to locate NAV_VE124

and yet for some reason (?<=\')((.*?)(?=End))

Does not produce any result...

Any thoughts would be greatly appreciated.

Also, I would like to combine these two searches so that I only grab the stuff after ' if the other condition is allowed, so any thoughts on how to do that would also be phenomenal :)

解决方案

(?<=\')((.|\s)*(?=End))

the problem is the multiline...not sure what regex tool your using but just do a (.|\s)* to match anything including newline. If \s doesn't work then find out what matches newline for your tool.
