JAVA读取XML文件 JDK1.4

XML code:

<?xml version="1.0" encoding="UTF-8" ?>
<Rot>
<name>张三</name>
<age></age>
<Tor>



Java code:

DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse (new File(filePath));
doc.getDocumentElement ().normalize ();
NodeList nodeList = doc.getElementsByTagName("Rot");
for(int i=0;i<nodeList.getLength();i++){
Node fatherNode=nodeList.item(i);
if(fatherNode.getNodeType()==Node.ELEMENT_NODE){
Element element = (Element)fatherNode;
NodeList nList = element.getElementsByTagName("age");
Element eElement = (Element)nList.item(0);
eElement.getTextContent();//这样没问题，但是jdk1.4不支持
eElement.getFirstChild().getNodeValue();//1.4支持但是,如果那个age节点里面没有值的话 直接报空值异常
}
}


但是现在 必须要在JDK 1.4的环境下运行
求解.......
