I'm trying to remove object nested in object in JSON file. However, I can not find any examples on the internet or on the official rapidjson page. My code is written on C++.
I have tried with the following code:
const Value& rootObject= document["root"];
const Value& settingsObject = extensionsObject;
settingsObject.RemoveMember();
But I am not sure what parameter to pass or how to initialize MemberIterator for exact element (as I already know the name of the object I want to remove).
Here is example of the JSON structure:
{
"root": {
"settings": {
"item1": {
"someInfo": 123
},
"item2": {
"someInfo": "string"
}
}
}
}
please chek my code.
Value Child_Obj(kObjectType); // creat object to but it inside another object
Child_Obj.SetObject(); // set it
Child_Obj.AddMember("Child Number", Value(15), Document->GetAllocator()); // add to child key and its value
Value Parent_Obj(kObjectType); // creat parent object that will have inside him the child object
Parent_Obj.SetObject(); // set it
Parent_Obj.AddMember("Parent Number", Value(10), Document->GetAllocator()); // add to parent key and its value
Parent_Obj.AddMember("Child", Child_Obj, Document->GetAllocator()); // add child object to parent object , "Child" as key and Child_Obj as value
// now the file looks like this :
/*
{
"Parent":
{
"Parent Number":10,
"Child":
{
"Child Number":15
}
}
}
*/
// let delete this child
Parent_Obj.RemoveMember("Child"); // here you will give it the key for the object you need to delete
// now its look like this :
/*
{
"Parent":
{
"Parent Number":10,
}
}
*/
// and for fun , if you want to iterate through object , you can do this :
Value::MemberIterator it = Parent_Obj.MemberBegin();
for (; it != Parent_Obj.MemberEnd(); ++it)
{
std::string str = it->name.GetString(); // this will give you the key for current child
