Re: [Boost-users] RegEx Bug

Can someone help check me on this code? The problem is that if I use a RegEx of:

^.*(?=.{4,})(?=(?:.*[A-Z]))(?=(?:.*[a-z])).*$

The results aren't as expected. I should expect that the password of Aa1 would fail, and yet it is passing the regex_match.

I borrowed this code from someone else's project and my concern is that Boost_RegEx doesn't work correctly with wide characters. Is this the case, or is there something else that is causing the problem.

What boost version are you using? The code below works as expected with Boost-1.32 and with the current cvs (soon to be released as 1.33). John. #include #include <iostream> int main() { std::wstring Password(L"Aa1"); boost::wregex wrePassword(L"^.*(?=.{4,})(?=(?:.*[A-Z]))(?=(?:.*[a-z])).*$"); boost::wsmatch what; unsigned int flags = boost::match_default; bool bMatch = regex_match(Password, what, wrePassword); if (bMatch) { std::cout << "PasswordFilter: Password matches specified RegEx"; } else { std::cout << "PasswordFilter: Password does NOT match specified RegEx"; } return 0; }
