How to parse bsoncxx::to_json?

[Yashashree Jadhav]

Hello,

I want to parse  data from bsoncxx::to_json(doc). Is any one have experience with this.

 mongocxx::cursor ncursor = collectionpddl.find({});
 
    for(auto doc : ncursor)
    {  
    
          if( bsoncxx::to_json(doc) == "_id")
          {
                 std::cout << "parse" << "\n";
                
          }
              
    }

Kindly help me out.

Thank you and Regards.

not sure what you are trying to do.  after to_json you will get a string something like 

  { "_id" : ... , "field2" : ... , ... }

generally you should only need to convert the bson to json if you are going to output to something outside your application, such as a .json file or perhaps another process via REST.

for debugging purposes start with something in the loop such as 

string s = to_json(doc);

cout << s << endl;

Hi -

Lets continue the existing discussion of this topic that is happening on mongodb-dev (https://groups.google.com/d/msgid/mongodb-dev/a9ba12fc-6129-4580-9ca7-bc50d8e9c7fe%40googlegroups.com?utm_medium=email&utm_source=footer) rather than starting a new thread here.

Thanks,

Andrew
