Reading more than one value with XPath and java 1.5

Question

Hello, I'm using XPath with Java 1.5 and I've some problems.
I do these things:
File xmlDocument = new File("c:/test.xml");
InputSource inputSource = new InputSource(new FileInputStream(xmlDocument));
XPathFactory factory = XPathFactory.newInstance();
XPath xPath = factory.newXPath();
int replication = Integer.parseInt(xPath.evaluate("/simulation/setup/replication", inputSource));
System.out.println(replication); // THIS WORKS!
warmuptime = Integer.parseInt(xPath.evaluate("/simulation/setup/warmuptime", inputSource));
System.out.println(warmuptime); // THIS DON'T WORK: javax.xml.xpath.XPathExpressionException
As I had written in the comments, the first time I call ".evaluate", it works, the second time it raises an exception.
The Xml is correct! The string "/simulation/setup/warmuptime" is correct!
I tryed to place a:
xPath.reset()
between the two "evaluate", but still doesn't work.
Can you give me an help? or suggest me an url where these things are explained in a simple way?
I just need to get some data from an XML file and XPath seems to be the quickest and easiest way.
Thanks for the help.

Are all the files in one directory? If so you can make a File object of the directory, get an array of all files in that directory (File has a method to do this). Then loop over your array and call a method that reads the File that you pass as a parameter.
