I posted earlier a question regarding XOR in perl strings ...

To help make clear the context of XOR here, could you please post a link to the prior (and possibly related) thread?

... I have a string of the type "hello %f.2f world". I want to xor everything but any regex that seems like [\%0-9a-z\.\ \=]. So in this case "hello" and "world" shoul be "xored" but not the rest.

I don't understand this. Do you want to do some string-xor operation(s) on some parts of the string that do not match the  [\%0-9a-z\.\ \=] character class? In that case, I can't see any character that doesn't match; the entire string matches, including 'hello' and 'world'.

If you have two parts of a string and you xor them together, what's supposed to happen to the result? WRT string-xoring, if you have two unequal-length strings to xor, what is supposed to happen? (I'm sure I have other areas of misunderstanding.)

Update: Oh, wait... Maybe I should have read Newest Nodes bottom-to-top instead of vice-versa. Does this pertain to Encrypt/decrypt string in C and Perl?

Give a man a fish:  <%-{-{-{-<
