转换的JSON数组选择

Question

So I made this code in Nodejs:

var stemidLength= JSON.memberList.members[0].length;

for (stemidIndex = 0; stemidIndex < stemidLength; stemidIndex++) {
  var steamID64Length= JSON.memberList.members[steamidIndex].steamID64.length;

  for (steamid64Index = 0; steamid64Index < steamid64Length; steamid64Index++) {
    steam.addFriend(steamID64[i]);
  }
}

And I'm trying to extract the steamid64s from the xml page here: http://steamcommunity.com/groups/Valve/memberslistxml/?xml=1 . I already converted the xml page into a JSON array.

What is wrong in my code? Getting error:

cannot read property 'members' of undefined.

EDIT: The JSON extracted array: http://pastebin.com/FECXEKMD

Thanks.

The JSON object is a built-in object for parsing JSON and converting strings to JSON. It does not have a memberList property.

I'll refer to the result of the XML to JSON conversion as steamUsers .

The IDs can be found in steamUsers.memberList.members[0].steamID64 . You can add the IDs with the code below:

xmlToJson(urlxml, function(err, data) {
    if (err) {
        return console.err(err);
    }

    var steamUsers = data;
    steamUsers.memberList.members[0].steamID64.forEach(function(memberID) {
        steam.addFriend(memberID);
        console.log(memberID);
    });
});
