Remove item from array based on it's value.

[nitanmarcel]

Having the json bellow, how can I get the array containing My Game 2 then delete the entire array from my json object?

The json array can get bigger so the item is not always in the same position so before deleting it I have to find it's index.

[
    {
        "title": "My Game",
        "url": "file://* or http*"
    },
    {
        "title": "My Game2",
        "url": "file://* or http*"
    }
]

Try this:

• Iterate through the array.
• Find the object where the key "title" has the value "My Game2" and stop iterating.
• If the iterator is not the past-the-end iterator, erase the object at that location.

auto it = j.begin();
for(; it != j.end(); ++it) {
    if(it->at("title") == "My Game2")
        break;
}

if(it != j.end()) j.erase(it);
