Can't get data from Yahoo weather.

I wanna get 7-day weather forcast data from Yahoo weather. I tried a thousand times but it simply does' t work. I cannot even make it with the following code. Could somebody help me with that? I appreciate it so much. I am using Processing 3.2.1 and windows 10.

                void setup(){
                  XML xml = loadXML("https:"+"//*%20from%20weather.forecast%20where%20woeid%3D4177");

                 XML yweather = xml.getChild("channel/item/yweather:condition");

                  int weatherCondition = yweather.getInt("code");

                  // Print the results


I tried example code from and it did work.

                // The following short XML file called "mammals.xml" is parsed 
                // in the code below. It must be in the project's "data" folder.
                // <?xml version="1.0"?>
                // <mammals>
                //   <animal id="0" species="Capra hircus">Goat</animal>
                //   <animal id="1" species="Panthera pardus">Leopard</animal>
                //   <animal id="2" species="Equus zebra">Zebra</animal>
                // </mammals>

                XML xml;

                void setup() {
                  xml = loadXML("mammals.xml");
                  XML[] children = xml.getChildren("animal");

                  for (int i = 0; i < children.length; i++) {
                    int id = children[i].getInt("id");
                    String coloring = children[i].getString("species");
                    String name = children[i].getContent();
                    println(id + ", " + coloring + ", " + name);

                // Sketch prints:
                // 0, Capra hircus, Goat
                // 1, Panthera pardus, Leopard
                // 2, Equus zebra, Zebra

And then I saved the weather data as xml file and load it in Processing. It still says Null Pointer Exception. Also I tried Yahoo Weather Library from com.onformative.yahooweather. But it doen' t have 7-day forcast. Thanks for your help!
