splitting this line using boost or regex - c++

Question

I am new to C++ and I am struggling to get this string to split. Looking to create a multimap that has book as the key. Noun and the definition after the "-=>>" would be a pair and so would verb and its definition. Here is the strings I can not seem to split correctly:
book|noun -=>> A set of pages.|verb -=>> To arrange something on a particular date.
bookable|adjective -=>> Can be ordered.
This is the code I am trying. I figured out this code is not properly loading the multimap, because when I print parts[0] both names are put into the same index. It seems regex is a simpler solution, but after plugging away at this for the last couple of hours I need some help.
while (getline(myfile, line)) {
string delimiters("|-=>>.");
vector<string> parts;
boost::split(parts, line, boost::is_any_of(delimiters));
name = parts[0];
partOfSpeech = parts[1];
definition = parts[2];
dictionary.emplace(make_pair(name, make_pair(partOfSpeech, definition)));
}
Any guidance or feedback is much appreciated

Answer 1

First split your line by |. The first resulting part is your name. Then got through all the other resulting parts and divide them into halves by -=>>. This will give you the first (partOfSpeech) and second (definition) halves of your pairs.
