XPath Question

Hi All,

I want to find out attribute values of specific nodes in xml files using xpath.

Suppose I have following xml file and I want to find out year values for all book nodes using xpath. I was trying to do this in following way.
DocumentBuilderFactory domFactory = DocumentBuilderFactory
.newInstance();
domFactory.setNamespaceAware(true);
DocumentBuilder build = domFactory.newDocumentBuilder();
Document d = build.parse("test.xml");
XPath xpath = XPathFactory.newInstance().newXPath();

XPathExpression ex = xpath.compile("//book[@year]");


NodeList result = (NodeList) ex.evaluate(d, XPathConstants.NodeSet);

for (int i = 0 ; i < result.getLength();++i) {
System.out.println("Year "i+" "+result.item(i).getNodeValue());
}
}


It gives me class cast exception.


My second question is

what is XPathConstants.DOM_OBJECT_MODEL and how to use it.

I want to do this using Xpath.


Please help me


Thanks and Regards


Rajesh
