This is implemented in my proposed super_string class.  Docs at:

Using super_string it looks like:

super_string s("<mark>Am<mark>A<mark>Test");
super_string::string_vector out_vec;
s.split("<mark>", out_vec);
//iterate on out_vec and process.

super_string is just a wrapper around std::string and boost libraries that do 
the heavy lifting.  If you want to do it yourself, you can use string_algo 
directly.  The relevent code that makes this work is:

  namespace alg = boost::algorithm;
  string predicate("<mark>");
  string input("<mark>Am<mark>A<mark>Test");
  vector<string> result;
  alg::iter_split(result, input,
                   alg::first_finder(predicate, alg::is_equal()));
    //iter_split will return entire string if no matches found

You can look at the implementation of super_string for hints...
