C++ StringTokenizer for a multichar separator [duplicate]

Split on substring

I want to separate an std::string by a two character separator, i.e. I'm looking for string tokenizer that can accept separators which are NOT a single character. Boost's tokenizer allows for multiple characters to be specified as separators, but this means that it'll consider any individual character as a separator, whilst what I want is to say that the separator is a particul开发者_运维百科ar sequence of characters, viz. a substring.

I'd initially thought I would quickly find the answer to this with a couple of google searches, but having just been proven wrong by a couple of wasted hours, I ask: ideas anyone?

QT's QString::split() can do this.
