std::string replace_with_literal(const std::string& text, const 
boost::regex& re, const std::string& replace)
{
std::string result;
sregex_iterator it(text.begin(), text.end(), re);
sregex_iterator end;
std::string::const_iterator last_end = text.begin();
while(it != end)
{
result.append(it->prefix().str());
result.append(replace);
last_end = it->suffix().first;
}
result.append(last_end, text.end());
return result;
}
