I'm trying to figure out the right way to use the xpath api
under 1.5.  I'm not sure I'm doing it the right way when a
node has multiple children -- I can get to the data, but my
technique seems kludgy.  The samples I found online tell you
how to get a NodeList, but don't really help you from there.

First, here is a sample document (XPathTest.xml):

<?xml version="1.0" encoding="utf-8"?>

<test>
 <one>This is a single item</one>

 <many>
   <item>This is one of many items #1</item>
   <item>This is one of many items #2</item>
   <item>This is one of many items #3</item>
 </many>
</test>

Here's an SSCCE.  The technique I use to get the single item
is easy enough, but I start to scratch my head when I go after
the many items:

import java.io.*;
import javax.xml.parsers.*;
import javax.xml.xpath.*;
import org.w3c.dom.*;

public class TestXPath  {
 public TestXPath(String configFileName) {
   try {
     DocumentBuilderFactory domFactory =
         DocumentBuilderFactory.newInstance();

     DocumentBuilder builder = domFactory.newDocumentBuilder();
     Document document = builder.parse(new File(configFileName));

     XPathFactory  xFactory = XPathFactory.newInstance();
     XPath xPath = xFactory.newXPath();

     String s1 = xPath.evaluate("/test/one", document);
     System.out.println("One item: " + s1);

     NodeList nodes = (NodeList)
        xPath.evaluate("/test/many/item",
        document, XPathConstants.NODESET);

     int length = nodes.getLength();
     System.out.println("Number of items: " + length);

     for (int i = 0; i < length; i++) {
       String s2 = xPath.evaluate("/test/many/item["
          + (i + 1) + "]", document);

       System.out.println("Many items #" + i + ": " + s2);
     }
   }
   catch (Exception x) { x.printStackTrace(); }
 }

 public static void main(String[] args) {
   new TestXPath("XPathTest.xml");
 }
}

I realize that a NodeList isn't Iterable, so I need to use a for loop
to get the individual items.  But the only thing I'm using the NodeList
for is to get a count -- I go back to the DOM to retrieve the actual
data.  This doesn't seem right.  Should I be using XPath on the NodeList
to get at the data more directly?  I tried various ways, and didn't get
anything to work.  Any advice?
