c++ parsing string with format

Question

i'm busy for a game for which i must parse a .txt file each row contains a format like this [goblin;2;30x1;1-5;20;5]

the values are as follows:

• name
• level
• attack (before the x the percentage of success, behind the x the amount of attacks in a single turn)
• damage (the minimum and maximum possible damage)
• defence (percentage a succesfull attack is still denied)
• hp

my current code is this:

    std::stringstream sstream(monsterLine);

    // Name is until the first comma.
    std::getline(sstream, monster.name, ';');

    // Then its spaces seperating the values.
    sstream >> monster.level;
    sstream >> monster.attackPoints;
    sstream >> monster.damagePoints;
    sstream >> monster.defensePoints;
    sstream >> monster.lifePoints;

this however only works if i format a string like goblin;2 30x1 1-5 20 5 how can i make it work with the above format?

Specific: how can i check if the current line is placed within [...] and strip them. how can i split the values by ; instead of (whitespace)

getline can be used for tokenization of a string.

if( (monsterLine.length() > 2) && 
    (monsterLine[0] == '[') && 
    (monsterLine[monsterLine.length() - 1] == ']') )
    {
        std::string szNewMonsterLine = monsterLine.substr(1, monsterLine.length() - 2);
        std::stringstream ss(szNewMonsterLine);

        if(getline(ss, monster.name, ';'))
        {   
            //some problem fetching data            
        }
        if(getline(ss, monster.level, ';'))
        {   
            //some problem fetching data            
        }
        if(getline(ss, monster.attackPoints, ';'))
        {   
            //some problem fetching data            
        }
        ...
        ...
        if(getline(ss, monster.lifePoints, ';'))
        {   
            //some problem fetching data
        }   
    }
