My Regular Expression is not working

Question

Here is the string i am trying to match

"NNNN.[LOOP]S[SENSOR] [TEXT]"

Here is the RegEx i am using

"NNNN.([^\n\r/.]*)S([^\n\r/.]*) ([^\n\r/.]*)"

I want this to match "[LOOP]", "[SENSOR]" and "[TEXT]"

However it matches "[LOOP]S[SEN", "OR]" and "[TEXT]"

Try this one:

NNNN\.(\[[^\s]+\])S(\[[^\s]+\])\s(\[[^\s]+\])

Note that you have to escape the dot "." and the square brackets "[" "]"

This will match: NNNN string, followed by a dot \. followed by a string (that doesn't contains spaces) between brackets (\[[^\s]+\]), followed by an S, followed by another string between brackets (\[[^\s]+\]), followed by a single space \s, followed by a third string between brackets (\[[^\s]+\]).
