[Boost-users] a little help with trimming strings

Hi, Is it possible using the trim() family of functions to remove not just white space, but some substring from the right of a string? For example, if I want to remove commas from the right: string str = "whatever,"; TrimRight(str, ","); // str == "whatever" now. or a full string to trim: string str = "hello world"; TrimRight(str, "world"); // str == "hello "; I could write these simple functions myself but am wondering if boost can do that already, Thanks, Mark
