Здраствуйте. Я решил написать парсер для файла вида: | Код |

Я сделал пользовательские классы для тегов FORECAST,PHENOMENA, PRESSURE, TEMPERATURE, WIND,RELWET. Атрибуты REPORT, TOWN и HEAT мне не нужны. Вот пример | Код |
public class Forecast {
Forecast(){this.day=new String("we");
this.month=new String("we");
this.year=new String("we");
this.hour=new String("we");
this.tod=new String("we");
this.weekday=new String("we");
this.pheno=new Phenomena();
this.press=new Pressure();
this.relw=new Relwet();
this.temp=new Temperature();
this.wind1=new Wind();}
Forecast(String a, String b, String c, String d, String e, String f){
this.day=a;
this.month=b;
this.year=c;
this.hour=d;
this.tod=e;
this.weekday=f;
this.pheno=new Phenomena();
this.press=new Pressure();
this.relw=new Relwet();
this.temp=new Temperature();
this.wind1=new Wind();
}
private String day, month ,year, hour, tod, weekday;
private Phenomena pheno;
private Pressure press;
private Relwet relw;
private Temperature temp;
private Wind wind1;
public Phenomena getPhenomena(){return pheno;}
public Pressure getPressure(){return press;}
public Relwet getRelwet(){return relw;}
public Temperature getTemperature(){return temp;}
public Wind getWind(){return wind1;}
public void setDay(String a){this.day=a;}
public void setPhenomena(Phenomena a){this.pheno=a;}
public void setPressure(Pressure a){this.press=a;}
public void setRelwet(Relwet a){this.relw=a;}
public void setTemperature(Temperature a){this.temp=a;}
public void setWind(Wind a){this.wind1=a;}
public void setMonth(String a){this.month=a;}

public void setWeekday(String a){this.weekday=a;}
public String getDay(){return day;}
public String getMonth(){return month;}
public String getYear(){return year;}
public String getHour(){return hour;}
public String getTod(){return tod;}
public String getWeekday(){return weekday;}
}

| Код |
public class Phenomena {

Классы PHENOMENA, PRESSURE, TEMPERATURE, WIND,RELWET построенны по одному принцыпу. У меня есть еще класс в котором хранится дополнительная инфа и масив обьектов класса FORECAST. | Код |
public class CitiesInfo{
boolean isForm;
int size;
private Forecast forec[];
private String name;
private String xml_file;
public void setForecast(Forecast data,int i){this.forec[i]=data;}
public Forecast getForec1(int i){return forec[i];}
public boolean getIsForm(){return isForm;}
public int getSize(){return size;}
public void setSize(int i){this.size=i;}
public void setIsForm(){this.isForm=true;}
CitiesInfo(String a, Forecast b, Forecast c, Forecast d,Forecast e){
this.isForm=false;
this.size=2;
this.name=a;
this.forec=new Forecast[4];
this.forec[0]=b;
this.forec[1]=c;
this.forec[2]=d;
this.forec[3]=e;
this.xml_file="nothing";
for(int i=0;i<4;i++)
