天气应用

Question

大家

好的，所以我正在创建一个天气应用程序，它从雅虎天气api获取信息。这是XML：http://weather.yahooapis.com/forecastrss?p=44310

P.S。最好在谷歌浏览器中打开它，因为它会将其显示为XML文件。

我正在尝试从XML中获取多个项目。我试图让信息显示完整的城市和州，但我该怎么做？

XML适用于我所在的地区，但我需要它才能与任何城市合作。

这是我的代码：

public class PanelBase extends libs.PanelBase
{
    private var vo:WeatherVO;
    private var _details:DetailsView;

    public function PanelBase()
    {
        super();

        // below is my settings for the input area where you have to enter your zip code
        // .text empties the field, .restrict keeps a person from using what ever 
        // is not added. in this case, the person can only use numbers from 0 to 9 only
        // .maxchars sets the number of possible items that a person can enter inside the input field.
        // buttonMode just creates the illusion of a button formed from a graphic
        this.tf_Zipcode.text = "";
        this.tf_Zipcode.restrict = "0-9";
        this.tf_Zipcode.maxChars = 5;
        this.btn_Enter.addEventListener(MouseEvent.CLICK, processZip);
    }

    // function for the button
    private function processZip(e:Event):void
    {
        // if the zip code area is wrong, inside of the text area above the zip code
        // will let you know that the zip entered is wrong, but if the zip code
        // you enter has less than 5 numbers, then you will be told there aren't enough numbers
        // then the zip code text field will empty itself.
        if(this.tf_Zipcode.text == null)
        {
            this.tf_Hint.text = "Sorry! Your zip code is invalid.";
        }
        else if(this.tf_Zipcode.text.length < 5)
        {
            this.tf_Zipcode.text = "";
            this.tf_Hint.text = "There are not enough numbers!"
        }
        else
        {
            this.removeChild(this.tf_Zipcode);
            this.addChild(this.tf_Zipcode);
            this.tf_Zipcode.text = "";
            //getImages();
            loadInfo();
        }
    }

    // function for loading the XML
    private function loadInfo():void
    {
        var ld:URLLoader = new URLLoader();
        ld.load(new URLRequest("http://weather.yahooapis.com/forecastrss?p=44310&u=f"));
        ld.addEventListener(Event.COMPLETE, parseInfo);
    }

    // function 
    private function parseInfo(e:Event):void
    {
        var xmlData:XML = XML(e.target.data);
        var ns1:Namespace = new Namespace("http://xml.weather.yahoo.com/ns/rss/1.0");
        var ns2:Namespace = new Namespace("http://xml.weather.yahoo.com/ns/rss/1.0");

        // parsing the information from the XML into the text fields 
        vo = new WeatherVO();
        vo.City = xmlData.channel.ns1::location.@city;
        vo.CurrentTemp = xmlData.channel.ns1::condition.@temp;
        vo.High = xmlData.item.channel.ns1::forecast.@high;
        vo.Low = xmlData.item.channel.ns1::forecast.@low;
        vo.Humidity = xmlData.channel.ns1::atmosphere.@humidity;
        vo.Wind = xmlData.channel.ns1::wind.@chill;
        vo.Rise = xmlData.channel.ns1::astronomy.@sunrise;
        vo.Set = xmlData.channel.ns1::astronomy.@sunset;
        vo.Tomorrow = xmlData.channel.item.ns2::forecast[1].@day;


        trace(xmlData)
        updateTextFields();

    }

    private function updateTextFields():void
    {
        //remove zip code view and then add result panel view


        _details = new DetailsView();
        this.addChild(_details);

        _details.tf_City.text = vo.City;
        _details.tf_CurrentTemp.text = vo.CurrentTemp;
        _details.tf_High.text = vo.High;
        _details.tf_Low.text = vo.Low;
        _details.tf_Humidity.text = vo.Humidity;
        _details.tf_Wind.text = vo.Wind;
        _details.tf_Rise.text = vo.Rise;
        _details.tf_Set.text = vo.Set;
        _details.tf_Tomorrow.text = vo.Tomorrow;

Answer 1

尝试将以下内容添加到parseInfo方法中：

vo.Region = xmlData.channel.ns1::location.@region;

trace (vo.City + ", " + vo.Region);
