C++ Check in Monster Spells

[Aspect]

How do I do this in TFS 1.5?

SpellList::const_iterator it = mType->spellAttackList.begin();
for(uint32_t i = 1; it != mType->spellAttackList.end(); ++it, ++i)

I know how the functions are called, but I didn't understand how it would work to do it this way in 1.5 since SpellList and spellAttackList are called in another way:

monsterType->info.attackSpells
std::vector<spellBlock_t> attackSpells;

What I'm trying to do is check if the monster's attacks have a "variable" called "key", in 0.3.6 I can do it this way:

std::string moveName = "";
    SpellList::const_iterator it = mType->spellAttackList.begin();
    for(uint32_t i = 1; it != mType->spellAttackList.end(); ++it, ++i)
    {
        if(it->key != key)
        {
            continue;
        }
        moveName = it->isName;
        break;
    }

But I would like to know how it works to do in 1.5?
