Var item = xml. childNodes. item (I );
Var nodeName = item. nodeName;
If (typeof (obj [nodeName]) = "undefined "){
Obj [nodeName] = xmlToJson (item );
} Else {
If (typeof (obj [nodeName]. length) = "undefined "){
Var old = obj [nodeName];
Obj [nodeName] = [];
Obj [nodeName]. push (old );
}
Obj [nodeName]. push (xmlToJson (item ));
