i have this xml document which has varying number of same named tags. how can i get the count of the child elements and the value of it.
<Question>
<QuestionText>ABC?</QuestionText>
<Option>A1 - XYZ</Option>
<Option>A2 - WXY</Option>
<Option>A2 - HJK</Option>
<ID>1</ID>
</Question>
<Question>
<QuestionText>ERY?</QuestionText>
<QuestionText>NNN?</QuestionText>
<QuestionText>KKKK?</QuestionText>
<ID>2</ID>
</Question>
The output should read...
ID:2 Has 1 QuestionText and 3 Option QuestionText 1:ABC? Option 1:A1 - XYZ Option 2:A2 - WXY Option 3:A2 - HJK
ID:1 Has 3 QuestionText and 0 option QuestionText 1.ERY? QuestionText 2.NNN? QuestionText 3.KKKK?
I tried, but this gives fault results
Element eElement = (Element) nNode;
for(int i=0;i<eElement.getChildNodes().getLength();i++){
System.out.println("NodeName:"+eElement.getNodeName());
System.out.println("Tag value:"+getTagValue("QuestionText",eElement));
System.out.println("Tag value:"+getTagValue("Option",eElement));
}
private static String getTagValue(String sTag, Element eElement){
NodeList nlList= eElement.getElementsByTagName(sTag).item(0).getChildNodes();
Node nValue = (Node) nlList.item(0);
return nValue.getNodeValue();
}
After doing some research I found the solution
Element eElement = (Element) nNode;
getTagValue("QuestionText",eElement);
getTagValue("Option",eElement);
private static void getTagValue(String sTag, Element eElement){
NodeList nlList = eElement.getElementsByTagName(sTag);
System.out.println("Size of nodelist:"+nlList.getLength());
for(int i=0;i<nlList.getLength();i++){
NodeList kList= eElement.getElementsByTagName(sTag).item(i).getChildNodes();
Node kValue = (Node) kList.item(0);
System.out.println("Node Value:"+kValue.getNodeValue());
}
}
What is the
getTagValue()
?Anyway, it is the best tutorial (How to read XML file in Java) for DOM parser in java for me. Have a look at this
Here is
getTagValue()
from that link
