Справка по Java с логикой в ​​обработчике XML SAX

Question

Я пытаюсь настроить обработчик SAX для анализа XML со следующей структурой:

<Hours>
  <Set name="BUSINESS">
        <MO>
              <Open>09:00:00</Open>
              <Close>17:00:00</Close>
        </MO>
        <TU>
              <Open>09:00:00</Open>
              <Close>17:00:00</Close>
        </TU>
        <WE>
              <Open>09:00:00</Open>
              <Close>17:00:00</Close>
        </WE>
        <TH>
              <Open>09:00:00</Open>
              <Close>17:00:00</Close>
        </TH>
        <FR>
              <Open>09:00:00</Open>
              <Close>17:00:00</Close>
        </FR>
        <SA/>
        <SU/>
  </Set>
  <Set name="LASTCOLLECTION">
        <MO>
              <Close>17:00:00</Close>
        </MO>
        <TU>
              <Close>17:00:00</Close>
        </TU>
        <WE>
              <Close>17:00:00</Close>
        </WE>
        <TH>
              <Close>17:00:00</Close>
        </TH>
        <FR>
              <Close>17:00:00</Close>
        </FR>
        <SA/>
        <SU/>
  </Set>
 </Hours>

Однако у меня возникают некоторые проблемы.Мой код действительно получит значения ОТКРЫТЬ и ЗАКРЫТЬ в МО, а не в другие дни недели.Кто-нибудь может найти изъян в моей логике?Вот мой код обработчика:

public void startElement(String uri, String localName, String qName,
        Attributes attributes) throws SAXException {

    if (localName.equalsIgnoreCase("Set")
            && attributes.getValue("name").equalsIgnoreCase(
                    "BUSINESS")) {
        inBusiness = true;
    } else if (localName.equalsIgnoreCase("Set")
            && attributes.getValue("name").equalsIgnoreCase(
                    "LASTCOLLECTION")) {
        inLastCollection = true;
    } else if (localName.equalsIgnoreCase("MO")) {
        inMonday = true;
    } else if (localName.equalsIgnoreCase("TU")) {
        inTuesday = true;
    } else if (localName.equalsIgnoreCase("WE")) {
        inWednesday = true;
    } else if (localName.equalsIgnoreCase("TH")) {
        inThursday = true;
    } else if (localName.equalsIgnoreCase("FR")) {
        inFriday = true;
    } else if (localName.equalsIgnoreCase("SA")) {
        inSaturday = true;
    } else if (localName.equalsIgnoreCase("SU")) {
        inSunday = true;
    } else if (localName.equalsIgnoreCase("Open")) {
        inOpen = true;
    } else if (localName.equalsIgnoreCase("Close")) {
        inClose = true;
    }

}

public void characters(char ch[], int start, int length)
        throws SAXException {

    value = value + new String(ch, start, length).trim();

}

public void endElement(String uri, String name, String qName)
        throws SAXException {

    if (inBusiness) {

        bHours = new BusinessHours();

        if (inMonday) {

            if (inOpen) {

Answer 1

On Line 116 Вы устанавливаете inBusiness = false - это будет установлено после понедельника открытия / закрытия.В следующий раз он завершится с ошибкой if (inBusiness) в строке 44.

Вместо использования логического значения inBusiness используйте индикатор int следующим образом:

private int curElement = 0;

public void startElement (String uri, String localName, String qName, атрибуты Attributes) выдает SAXException {

if (localName.equalsIgnoreCase("Set")
        && attributes.getValue("name").equalsIgnoreCase(
                "BUSINESS")) {
    curElement = 1;
} else if (localName.equalsIgnoreCase("Set")
        && attributes.getValue("name").equalsIgnoreCase(
                "LASTCOLLECTION")) {
    curElement = 2;
}

......

}

publicvoid endElement (String uri, String name, String qName) выдает SAXException {

if (curElement == 1) {

    ....
    //Remove inBusiness= false;
} else if (curElement == 2) {
    ...
    //Remove inLastCollection = false;
}

}
