Hello, I'm using boost's regex for a school project (they encourage us to use boost) Boost 1.34 is what is available on the school computers (unless fedora 9 promotes a newer version out of testing before Tuesday.) I'm trying to use a non-greedy quantifier in a regex. Here is an example from my code: string input=string("/blog/2008/../"); string expr=string("/.*?/\\.\\./"); string replacement=string("/"); std::ostringstream stream(std::ios::out | std::ios::binary); std::ostream_iterator stream_iterator(stream); boost::regex pattern(expr, boost::regex::perl); boost::regex_replace(stream_iterator, input.begin(), input.end(), pattern, replacement, boost::match_default | boost::format_all); string result=stream.str(); The expected output is "/blog/". I am getting "/". I've played with different arguments to the boost::regex constructor, but I can't seem to get it to output a correct result. I did notice that in the notes for the boost regex library in 1.34 that there was a bug fixed related to non-greedy quantifiers, so I'm fairly confident that I just have a problem with my own code. A tarball can be provided with a "ready-to-compile" example snippet and test case. Then again, it could just as likely be a problem with the regular expression itself, though I checked, re-checked, and double checked that this is the correct syntax for the perl mode in the boost regex library. Thanks for any input! Jeff Anderson
