[YouTube-API] Re: Parsing youtube data with C++ and Jsoncpp

Oh that's correct, I don't know how I got valid json last time. I've some experience parsing twitter data which had many multiple values but for some reason raw parsing of youtube data e.g. with many fields named yt$username seems to be hard.

When I tried parse it straight from the data provided by youtube I got only null results :S

as

data = value["feed"]["yt$username"];
Only way to even get the first username I needed to parse it first value["feed"]["entry"]; and username out of that.

Would you have any easier idea about this ?

I'm not quite sure is this right place to ask about this but my problem is following:

Here is an example feed that I would like to parse:https://gdata.youtube.com/feeds/api/users/aniBOOM/subscriptions?v=2&alt=json

You can check it with http://json.parser.online.fr/ to see what it contains.

I have a small problem while parsing data feed provided by youtube. First issue was the way the youtube provided the data wrapped inside feed field and because of that I couldn't parse the username straight from original json file so I had to parse first entry field and generate new Json data from that.

Anyway the problem is that for some reason that doesn't include more than the first username and I don't know why because if you check that feed on online parser the entry should contain all the usernames.

       data = value["feed"]["entry"];
        Json::StyledWriter writer;
        std::string outputConfig = writer.write( data );
//This removes [ at the beginning of entry and also last ] so we can treat it as a Json data
        size_t found;
        found=outputConfig.find_first_of("[");
        int sSize = outputConfig.size();            
        outputConfig.erase(0,1);
        outputConfig.erase((sSize-1),sSize);

        reader.parse(outputConfig, value2, false);

        cout << value2 << endl;

        Json::Value temp;
        temp = value2["yt$username"]["yt$display"];
        cout << temp << endl;

        std::string username = writer.write( temp );
        int sSize2 = username.size();           
        username.erase(0,1);
        username.erase((sSize2-3),sSize2);

But for some reason [] fix also cuts the data I'm generating, if I print out the data without removing [] I can see all the users but in that case I can't extract temp = value2["yt$username"]["yt$display"];
