J'ai utilisé l'analyseur Java Sax, mais j'essaie d'implémenter Android avec ce XML.Essayer de comprendre l'analyseur Sax d'Android

Je partais de l'exemple à l'adresse (http://www.ibm.com/developerworks/opensource/library/x-android/index.html
Je ne sais pas comment je prends différents niveaux au sein du XML que j'ai une classe WeatherData qui stocke toutes les informations que j'ai besoin.:
public class WeatherData {
//instance data
@SuppressWarnings("unused")
private final String DEB_TAG = "WeatherData.java";
public Location location;
public Current current;
public List<Forecast> forecast;
public WeatherData(){
location = new Location();
current = new Current();
forecast = new ArrayList<Forecast>();
}
public class Location {
public String time;
public String city;
public String state;
public Location(){
}
public Location(String time, String city, String state){
this.time = time;
this.city = city;
this.state = state;
}
public String getTime() {
return time;
}
public void setTime(String time) {
this.time = time;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
}
public class Current {
public String temp;
public String realfeel;
public String humidity;
public String icon;
public String getTemp() {
return temp;
}
public void setTemp(String temp) {
this.temp = temp;
}
public String getRealfeel() {
return realfeel;
}
public void setRealfeel(String realfeel) {
this.realfeel = realfeel;
}
public String getHumidity() {
return humidity;
}
public void setHumidity(String humidity) {
this.humidity = humidity;
}
public String getIcon() {
return icon;
}
public void setIcon(String icon) {
this.icon = icon;
}
public Current(){
}
public Current(String temp, String realfeel, String humidity, String icon){
this.temp = temp;
this.realfeel = realfeel;
this.humidity = humidity;
this.icon = icon;
Log.d("DEB_TAG", "Value of temp inside Current is " + temp);
}
}
public class Forecast{
// Forecast member variables
public String day_d;
public String icon_d;
public String high_d;
public String low_d;
public String obsDate_d;
public String getDay_d() {
return day_d;
}
public void setDay_d(String dayD) {
day_d = dayD;
}
public String getIcon_d() {
return icon_d;
}
public void setIcon_d(String iconD) {
icon_d = iconD;
}
public String getHigh_d() {
return high_d;
}
public void setHigh_d(String highD) {
high_d = highD;
}
public String getLow_d() {
return low_d;
}
public void setLow_d(String lowD) {
low_d = lowD;
}
public String getObsDate_d() {
return obsDate_d;
}
public void setObsDate_d(String obsDateD) {
obsDate_d = obsDateD;
}
}
public Forecast createForecast(){
return new Forecast();
}
}
ce que je ne comprends pas comment à l'étape dans les différents niveaux de mon XML. J'ai ma balise racine adc_database qui contient mon o Pening et fermetures de LOCAL, CURRENTCONDITIONS et PRÉVISION, où PRÉVISION a plusieurs prévisions quotidiennes. Voici mon code jusqu'à présent ...
public class AndroidSaxFeedParser extends BaseFeedParser {
public AndroidSaxFeedParser(String feedUrl) {
super(feedUrl);
}
public List<WeatherData> parse() {
final WeatherData currentData = new WeatherData();
RootElement root = new RootElement("rss");
final List<WeatherData> conditions = new ArrayList<WeatherData>();
Element adc_database = root.getChild("adc_database");
Element item = adc_database.getChild(LOCAL);
item.setEndElementListener(new EndElementListener(){
public void end() {
conditions.add(currentData.copy());
}
});
item.getChild(CITY).setEndTextElementListener(new EndTextElementListener(){
public void end(String body) {
currentData.location.setCity(body);
}
});
item.getChild(ADMINAREA).setEndTextElementListener(new EndTextElementListener(){
public void end(String body) {
currentData.location.setState(body);
}
});
try {
Xml.parse(this.getInputStream(), Xml.Encoding.UTF_8,
root.getContentHandler());
} catch (Exception e) {
throw new RuntimeException(e);
}
return conditions;
}
}
Si quelqu'un peut aider à expliquer le code SAX et comment j'aller dans les différents niveaux ou pourrait me pointer vers un autre exemple qui va plus loin que d'un niveau serait génial!
