Ok, I got Idea how to get some info from yahoo weather rss . In the script block I have changed

<fx:Declarations>
    <!-- Place non-visual elements (e.g., services, value objects) here -->
    <s:HTTPService id="weatherService"
                   url="{BASE_URL}"
                   resultFormat="e4x"
                   result="weatherService_resultHandler(event)"
                   fault="weatherService_faultHandler(event)"
                   showBusyCursor="true">
        <s:request xmlns="">
            <w>{woeidInput.text.toString()}</w>             
        </s:request>
    </s:HTTPService>
</fx:Declarations>

now in script block I I did like this:

            protected function weatherService_resultHandler(event:ResultEvent):void
        {
            // TODO Auto-generated method stub
            var result_weather_data_xml:XML = new XML(event.result);
            var cityNameData:XMLList = result_weather_data_xml.descendants().attribute("city");
            var countryNameData:XMLList = result_weather_data_xml.descendants().attribute("country");
            var tempCData:XMLList = result_weather_data_xml.descendants().attribute("temp");
            var descripData:XMLList = result_weather_data_xml.descendants().attribute("text");
            var humidData:XMLList = result_weather_data_xml.descendants().attribute("humidity");

            var image:String;
            cityName.text=cityNameData + ", "+ countryNameData;
            tempData.text = tempCData+"\u00B0"+"F";
            descData.text = descripData[0];
            HumidityData.text = humidData+"%";
        }

and for each thing which you want in in your app is to give attribute("NAME OF THING")
