I am trying to set up a SAX Handler to parse XML with the following structure: <Hours> <Set name=\"BUSINESS\">

I am trying to set up a SAX Handler to parse XML with the following structure:

<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>

        <SA/>
        <SU/>
  </Set>

I am running into some problems, however. My code will only really get the value of OPEN and CLOSE in MO, not in any of the other days of the week. Can anyone find a flaw in my logic? Here is my handler code:

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();

On Line 116 You are setting inBusiness = false - which will get set after monday's open/close. Next time around it fails the if(inBusiness) on line 44.

Instead of using a inBusiness boolean, use a int indicator as follows:

private int curElement = 0;

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

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

......

}

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

if (curElement == 1) {

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

}
