Hi,
I have the following regular expression for matching a URI/URL(works  
fine with PCRE, note I have escaped ++ to work with boost::regex but  
otherwise unchanged):

const boost::regex regex_username_password(
    "("
       "(?:"
          "[a-zA-Z0-9_.!~*'()&=+$,;?/-]\\+\\+"
       "|"
          "%[0-9a-fA-F]{2}"
       ")+"
     ")"
    "(?:" ":"
         "("
         "(?:"
             "[a-zA-Z0-9_.!~*'()&=+$,-]\\+\\+"
         "|"
            "%[0-9a-fA-F]{2}"
         ")*"
       ")"
     ")?"
     "@"
);

For the life of me I cannot figure out why it isn't working. The  
boost::test results looks like so:

failed [10.1.2.33 != test]
... error in "test_http_url": check url == u.to_string() failed [sip:test_at_10.1.2.33 
  != sip:test]
... error in "test_http_url": check url == get_uri(u) failed [sip:test_at_10.1.2.33 
  != sip:test]

I believe it is the regex, here is the iterator position, etc...

std::string(*it, str.end()) == ":test_at_10.1.2.33"

iterator position = ':'

if (boost::regex_search(it, str.end(), matches, UsernameAndPassword))
{
        assert(0); // never reached
}

Any help here would be great, thanks!
