私はこれまで正常に機能していたxmlファイルを解析するためにSAXパーサーを使用していますが、何らかの理由で写真タグの画像URLを解析しません（URLを文字列として解析したい）。誰かが理由を知ってくれることを望んでいましたか？どんな助けでもいただければ幸いです。これはXMLです：

これが私のSAXパーサーのコードです。
public class XMLHandler extends DefaultHandler {
String elementValue = "";
Boolean elementOn = false;
Boolean inPromises = false;
public static XMLGettersSetters data = null;
public static ArrayList<XMLGettersSetters> candList = new ArrayList<XMLGettersSetters>();
public static ArrayList<XMLGettersSetters> getCandList() {
return candList;
}
@Override
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
elementOn = true;
if (localName.equals("candidate"))
{
data = new XMLGettersSetters();
} else if (localName.equals("promises")) {
inPromises = true;
}
}
/**
* This will be called when the tags of the XML end.
**/
@Override
public void endElement(String uri, String localName, String qName)
throws SAXException {
elementOn = false;
/**
* Sets the values after retrieving the values from the XML tags
* */
if (localName.equalsIgnoreCase("name"))
data.setName(elementValue);
else if (localName.equalsIgnoreCase("office"))
data.setOffice(elementValue);
else if (localName.equalsIgnoreCase("photograph"))
data.setPhotograph(elementValue);
else if (localName.equalsIgnoreCase("promise")) {
if(inPromises){
data.setPromise(elementValue);
}
}
else if (localName.equalsIgnoreCase("statement"))
data.setStatement(elementValue);
else if(localName.equalsIgnoreCase("candidate"))
candList.add(data);
}
/**
* This is called to get the tags value
**/
@Override
public void characters(char[] ch, int start, int length)
throws SAXException {
if (elementOn) {
elementValue = new String(ch, start, length);
elementOn = false;
}
}
もっと：

this.promises = promises;
this.statement = statement;
}
public String getName() {
