正则表达式匹配除特定标志格式的单词之外的所有内容

Question

I need a regex that can match everything else except the random flags..

All flags have this format, starts with FLAG and ends in ;

FLAG:random_token;

Example:

hello
hello world
lorem ipsum dolor sit amet
FLAG:xyz6767abcd45xyz; and lorem
lorem ipsum dolor
FLAG:abc123; and hello there,..
hello there....

output Im trying to obtain:

hello
hello world
lorem ipsum dolor sit amet
 and lorem
lorem ipsum dolor
 and hello there,..
hello there....

So far I've tried:
^(?:FLAG.(?*;).).*
and
(?.:*\bFLAG..*$)^.*$

But it fails to extract the strings after the semicolon in FLAG:random_token;
Any help would be appreciated

And I've tried deleting all Flags from the block, but I needed the token values later and Also thought regex would be the best fit.

One way to do this would be to remove the flags from the input string, using String.replace and a regex to match the FLAG: and random token (everything to the next ; ), you can then use a callback function to store the tokens as they are found:

 str = `hello hello world lorem ipsum dolor sit amet FLAG:xyz6767abcd45xyz; and lorem lorem ipsum dolor FLAG:abc123; and hello there,.. hello there....`; const tokens = []; str = str.replace(/FLAG:([^;]+);/g, (_, p1) => { tokens.push(p1); return ''; }); console.log(str); console.log(tokens);
