Actualy you can do it without regex. You need to use token_finder and find_format.


string strPath=find_format_all_copy(
   token_finder(is_any_of("\\/"), token_compress_on),

//strPath == C:\abc\def\ghi


Using the regex_finder is also possible, but you will not gain much more compared to using regex library directly.
