I have this regex: [\\s\\S-[<>]]*
Could you please help me understand what does this expression stand for? From what I see it means a character class formed of spaces and a range from non-space characters to < or >?
It doesn't make much sense..
Thanks!
This is a variant only supported by a few regex engines (.NET, JGSoft, XML Schema and XPath but not for example native Java regex), and it's called character class substraction .
For example,
[A-Z-[EFG]]
matches any letter from A
to Z
except E
, F
or G
.
But in your case, it really doesn't make much sense because [\\s\\S]
matches any character - the same result (in any regex flavor) can be achieved by
[^<>]*
