我知道这次被问了很多次,但我仍然无法让它发挥作用.我将xml字符串转换为Document对象,然后解析它.这是代码:

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.*;

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
try
{
  builder = factory.newDocumentBuilder();  
  Document document = builder.parse( new InputSource( new StringReader( result ) ) );
  Node head = document.getFirstChild();
  if(head != null)
  {                  
    NodeList airportList = head.getChildNodes();      
    for(int i=0; i<airportList.getLength(); i++) {
    Node n = airportList.item(i);                        
    Element airportElem = (Element)n;
  }
}
catch (Exception e) {
  e.printStackTrace();
} 

当我将Node对象n转换为Element时,我得到一个异常java.lang.ClassCastException:org.apache.harmony.xml.dom.TextImpl不能转换为org.w3c.dom.Element.当我检查Node对象的节点类型时,它表示Node.TEXT_NODE.我相信它应该是Node.ELEMENT_NODE.我对吗？

那么我如何将Node转换为Element,所以我可以做像element.getAttribute("attrName")这样的事情.

这是我的XML:
