用Dom4j 讀取xml

public class Demo {
public static void main(String[] args) throws Exception {
SAXReader reader = new SAXReader();
Document document = reader.read(new File("histdata.xml"));
Element root = document.getRootElement();

Iterator it = root.elementIterator();
while (it.hasNext()) {
Element element = (Element) it.next();

System.out.println("Traffic Total (speed): " + element.elementText("value"));
System.out.println();
}
}
}

运行结果：
Traffic Total (speed):900,605 MByte
Traffic Total (speed):1,045,356 MByte
Traffic Total (speed):968,420 MByte
Traffic Total (speed):929,250 MByte
Traffic Total (speed):897,072 MByte

属性名称相同，一直取到Traffic Total (volume)，我是需要Traffic Total (speed)的值
请问怎么解决??
