Example string: [China] code - 001-02 - [code - 002-02 France] + [British] code - 003-02
Requirements: I need to replace the symbol "-", but "-" of the code - 001-02 cannot replace, after the replacement string should be like this:
[China] code - 001-02 [code - 002-02 France] [British] code - 003-02

Thank you thank you very much!

CodePudding user response:

1/f, reference for emotion unavoidably lonely tears don't reply:

replace have anything to do with regular

Would you?
Regex. Replace (string, "regular", "")

CodePudding user response:

(? <=\]). *? (?=\ [)

CodePudding user response:

refer to the third floor and foliage quiet reply:

(? <=\]). *? (?=\ [)

Thank you very much!
Sorry, I describe the problem is not clear, then add:
Actually needs a bit more complicated, such as string could be like this: [China] code - 001-02. [& amp; 01] - [code - 002-02 France] [& amp; 02] + [British] code - 003-02. [& amp; 03]
After processing: [China] code - 001-02. [& amp; 01] [French] code - 002-02. [& amp; 02] [British] code - 003-02. [& amp; 03]
So I need to find the specific characters. (? <=\]). *? (?=\ [) cannot meet this expression,

CodePudding user response:

Don't know why we can't match: if with a plus sign or other you can, can't it happened that a minus sign (? <=\]) \ - *? (?=\ [)

CodePudding user response:

Is that right

CodePudding user response:

Oneself fumble, (? <=\]) - *? (?=\ [) can, originally a minus sign is not a metacharacter, also solved the problem, but still not perfect,
If the character is like this: [China] code - 001-02. [& amp; 01] - aa [code - 002-02 France] [& amp; 02] + [British] code - 003-02. [& amp; 03]
Can not match,

CodePudding user response:

The

reference from the 6th floor the foliage silent response:

is that right

Thank you very much, just want to continue to ask, see the 7th floor

CodePudding user response:

 let str123="[China] code - 001-02 - [code - 002-02 France] + [British] code - 003-02" 
Str123. Replace (/\] + [-] \ [/g, "] [") 

Look in the console to run
