getting node value exception

<amount currency="USD">1000500</amount> 

while parsing above string i am getting only attribute value .when i try to get node value null pointer exception

for getting node value using

 NodeList amountList= estimateElement.getElementsByTagName("amount");
 Element amtElement= (Element)amountList.item(0);
 String amount=amtElement.getFirstChild().getnodevalue()

Please try this. I assume that it is true:

 NodeList list = estimateElement.getElementsByTagName("amount").item(0).getChildNodes();
 Node node = (Node) list.item(0); 

 String value  = node.getNodeValue();

Element amtElement= (Element)amountList.item(0);

seems to be your element - so why are you calling getFirstChild()?

try this:

String amount=amtElement.getnodevalue()

have you checked out jdom? it has a nice documentation and is easy to use..

Try using the getTextContent() method:

NodeList amountList= estimateElement.getElementsByTagName("amount");
Element amtElement= (Element)amountList.item(0);
String amount=amtElement.getTextContent();
