XPathの場合？

<?xml version="1.0" encoding="Shift_JIS"?>

<config>

    <jdbc id="dev">

        <url>jdbc:oracle:oci8:@asan</url>

        <user>asan</user>

        <pass>asan</pass>

    </jdbc>

</config>
import javax.xml.parsers.*;

import org.w3c.dom.*;

import org.apache.xpath.*;
class XPathTest2 {

    public static void main(String[] args) throws Exception {

        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

        factory.setNamespaceAware(true);

        DocumentBuilder builder = factory.newDocumentBuilder();

        Document doc = builder.parse("config.xml");

        String url  = XPathAPI.eval(doc, "/config/jdbc[@id='dev']/url").toString();

        String user = XPathAPI.eval(doc, "/config/jdbc[@id='dev']/user").toString();

        String pass = XPathAPI.eval(doc, "/config/jdbc[@id='dev']/pass").toString();

    }

}

一応取れるけど、XPathってこういう使い方でいいのかな？
