Android weather forecast and Data Processing

Google weather api is used in the process of writing the android weather forecast program, while the data obtained by parsing the xml file with sax is in English. The problem of data conversion and display occurs here.
For example: Query weather http://www.google.com/ig/api in Wuhan? The xml data obtained by weather = wuhan is: <? Xml version = "1.0"?>
-<Xml_api_reply version = "1">
-<Weather module_id = "0" tab_id = "0" mobile_row = "0" mobile_zipped = "1" row = "0" section = "0">
-<Forecast_information>
<City data = "Wuhan, Hubei"/>
<Postal_code data = "wuhan"/>
<Latitude_e6 data = ""/>
<Longitude_e6 data = ""/>
<Forecast_date data = "2011-09-09"/>
<Current_date_time data = "21:00:00 + 0000"/>
<Unit_system data = "SI"/>
</Forecast_information>
-<Current_conditions>
<Condition data = "Multi-cloud"/>
<Temp_f data = "72"/>
<Temp_c data = "22"/>
<Humidity data = "humidity: 78%" type = "humidity" text = "humidity"/>
<Icon data = "/ig/images/weather/cn_cloudy.gif"/>
<Wind_condition data = "wind direction: Northeast China, wind speed: 4 meters/second"/>
</Current_conditions>
+ <Forecast_conditions>
-<Forecast_conditions>
<Day_of_week data = "Saturday"/>
<Low data = "20"/>
<High data = "29"/>
<Icon data = "/ig/images/weather/chance_of_rain.gif"/>
<Condition data = "rain may exist"/>
</Forecast_conditions>
-<Forecast_conditions>
<Day_of_week data = "Sunday"/>
<Low data = "22"/>
<High data = "29"/>
<Icon data = "/ig/images/weather/chance_of_storm.gif"/>
<Condition data = "A storm may exist"/>
</Forecast_conditions>
-<Forecast_conditions>
<Day_of_week data = "Monday"/>
<Low data = "23"/>
<High data = "31"/>
<Icon data = "/ig/images/weather/chance_of_storm.gif"/>
<Condition data = "A storm may exist"/>
</Forecast_conditions>
</Weather>
</Xml_api_reply>
The data obtained after parsing with sax is:
Wuhan, Hubei
Overcast (Multi-cloud)
23:00:00 + 0000
Fri (Friday)
Wind: NE at 9 mph (indicating Wind direction and Wind speed)
Humidity: 87% (Humidity)
For display, the corresponding conversion is required. Now I have posted my conversion code, hoping to benefit the public.
