how to generalise this code

[harishak reddy]

XPathFactory factory = XPathFactory.newInstance();
XPath xpath = factory.newXPath();

//first

XPathExpression expr
= xpath.compile("//Pool[@name='BLR' and @enabled='true']/*/text()");



Object result = expr.evaluate(doc, XPathConstants.NODESET);
NodeList nodes = (NodeList) result;

System.out.println("pool name BLR and enabled True");

for (int i = 0; i < nodes.getLength(); i++) {
System.out.println(nodes.item(i).getNodeValue());

}
I have many XPathExpression like expr1 ,expr2 etc to read and display.how can i generalise this code? I am new to java.Can any one give a solution
Thank you !
