Regex 正则表达式：匹配不包含特定字符串

通过使用正则表达式，我希望获得出现以下字符序列的所有索引：

FORALL ... in ... : 

//“FORALL”和“in”之间可能有空格和非单词字符，如“，”

例如： 找到以下三个：

对于所有我你可以试试这个正则表达式吗？（这是一个文本字符串）

"(^FORALL[<=|>=|<|>|==|!=](?!.*in).*in$)((?!.*\\:).*\\:$ )"

^(FORALL [^<=>,: ]+) *[<=>,]+ *([^<=>,: ]+)\s+in\s+([^,:]+)[^:]*:$

^             # Beginning of string
(             # 1st capture begins
  FORALL      # Match FORALL and a space
  [^<=>,: ]+  # Any characters except <=>,: or space
)             # 1st capture ends
 *            # Any spaces
[<=>,]+ *     # Any characters of <=>, followed by any spaces
(             # 2nd capture begins
  [^<=>,: ]+  # Any characters except <=>,: or space
)             # 2nd capture ends
 +in +        # Match in surrounded by spaces
([^,:]+)      # Match any non , or : characters
[^:]*:        # Match any non : characters, then match a :
$             # End of string
