regex to get all between @ and @ in multilines text-CodePudding

i hope you're fine.

example i have a text with tags @tag i want to get all text between the tags as parts (not as one, look at the picture at the end, at the top, the result is 4 matches and not one). the problem is inside the text of every tag maybe contains the symbol @, and this will cut my result matches.

i tried several times with different regex but alwas without success

the final regex i use is :

((^(@))|[^\"]@)[^(@)] \}\n

the example centent text (that i use for trying) :

@main.xml

and this is picture show my problem

i want to get the whole parts between @tag1 and @tag2,3,4...ect, how can i deal with the symbol @ if it is inside the content of tag ?

CodePudding user response：

I am not quite sure of the use of [^\"]@ in your expression... What is its purpose? could you provide an example?

Anyway you have to remove @ from the list of excluded characters. and change the way you look a the end of your section. Try:

^@[^(] ?\}\n(?=\@|$)

^@ matches @ at the beginning of a line
[^(] ? matches any character expect ( one or more times until (? makes it lazy) the next occurrence of the next element...
\}\n your segments always end with a curly bracket followed by a new line
(?=\@|$) the critical part: a lookahead that ensures the following element is either a @ (new segment) or the end of the file, without capturing it. That way you don't cut a segment before its end and you can still capture the beginning of the next segment.

CodePudding user response：

Use

(?m)^@. (?:\n. )*

See regex proof.

EXPLANATION

--------------------------------------------------------------------------------
  ^                        the beginning of the line due to (?m)
--------------------------------------------------------------------------------
  @                        '@'
--------------------------------------------------------------------------------
  .                        any character except \n (1 or more times
                           (matching the most amount possible))
--------------------------------------------------------------------------------
  (?:                      group, but do not capture (0 or more times
                           (matching the most amount possible)):
--------------------------------------------------------------------------------
    \n                       '\n' (newline)
--------------------------------------------------------------------------------
    .                        any character except \n (1 or more times
                             (matching the most amount possible))
--------------------------------------------------------------------------------
  )*                       end of grouping
