[Boost-users] How do I use regex to match two consecutive newlines?

I've tried matching like this:

        std::string input = filecontents;
        boost::regex re_paragraphs("\\n\\n");
        
        boost::sregex_token_iterator input_token_it(input.begin(), input.end(), 
re_paragraphs, -1);
        boost::sregex_token_iterator end_token_it;
        
        for( ; input_token_it != end_token_it; input_token_it++ )
        {
                output += "TOKEN FOUND"
        }
        return output;

But this never works. It matches when I use a part of a word as a token. 
The problem is that it's just not matching the newlines. I've looked 
into the input's hex and there are indeed two newline chars consecutively.

I think I'm missing something obvious. Anyone have any idea?
