Dieser Code retured nur ein "Frage" Tag-Element, aber ich habe noch 9 Frage-Element in der XML-Datei.Was ist das Falsche hier drin? Muss ich loop.Weil ich überprüft die Schleife, es Schleifen nur einmal.Was ist das Problem? Ich bin herauszufinden.java dom parser bekommt nur die erste Entität
Hier ist meine xml:
<Results>
<question>
<eno>3</eno>
<qno>1</qno>

</question>
</Results>
mein Quellcode:
NodeList listOfQuestions = doc.getElementsByTagName("question");
for(int s=0; s<listOfQuestions.getLength(); s++)
{
System.out.println(listOfQuestions.getLength());
Node firstQuestionNode = listOfQuestions.item(0);
if(firstQuestionNode.getNodeType() == Node.ELEMENT_NODE){
Element firstQElement = (Element)firstQuestionNode;
NodeList enoList = firstQElement.getElementsByTagName("eno");
Element enoElement =(Element)enoList.item(s);
NodeList enosList = enoElement.getChildNodes();
String eno=((Node)enosList.item(s)).getNodeValue().trim();
System.out.println(eno);
NodeList qnoList = firstQElement.getElementsByTagName("qno");
Element qnoElement =(Element)qnoList.item(s);
NodeList qnosList = qnoElement.getChildNodes();
String qno= ((Node)qnosList.item(s)).getNodeValue().trim();
System.out.println(qno);
NodeList qtextList = firstQElement.getElementsByTagName("qtext");
Element qtextElement =(Element)qtextList.item(s);
NodeList qtextsList = qtextElement.getChildNodes();
String qtext= ((Node)qtextsList.item(s)).getNodeValue().trim();
System.out.println(qtext);
NodeList correctAnswerList = firstQElement.getElementsByTagName("correctAnswer");
Element correctAnswerElement =(Element)correctAnswerList.item(s);
NodeList correctAnswerElementList = correctAnswerElement.getChildNodes();
String correctAnswer= ((Node)correctAnswerElementList.item(s)).getNodeValue().trim();
System.out.println(correctAnswer);
int i=st.executeUpdate("insert into question(eno,qno,qtext,correctAnswer) values('"+eno+"','"+qno+"','"+qtext+"','"+correctAnswer+"')");
System.out.println("s is"+s);
}
