[Boost-users] [string_algo] replace repeated char with single instance?

Am I required to use regex_finder to replace repeated chars with a single instance? I'm trying to cleanup a string for use with filesystem::path, for example: C:\\abc///def\\ghi => C:\abc\def\ghi There may be mixed forward and back-slashes. These are from environment variables that apparently are required by our use of NutCracker to support legacy apps under windows. If I need to use regex_finder what are the benefits of the string_algo versus just using the regex library? Thanks, Jeff
