您可以使用Java SE完成以下工作：
import java.io.StringReader;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathFactory;
import org.xml.sax.InputSource;
public class Demo {
public static void main(String[] args) throws Exception {
String xml = "<car><manufacturer>toyota</manufacturer></car>";
String xpath = "/car/manufacturer";
XPath xPath = XPathFactory.newInstance().newXPath();
assertEquals("toyota",xPath.evaluate(xpath, new InputSource(new StringReader(xml))));
}
}
