孙鑫XML视频教程中关于DOM例子的一点错误

源代码如下：




import java.io.File;


import java.io.IOException;




import javax.xml.parsers.DocumentBuilder;


import javax.xml.parsers.DocumentBuilderFactory;


import javax.xml.parsers.ParserConfigurationException;

import javax.xml.transform.TransformerFactory;


import javax.xml.transform.dom.DOMSource;


import javax.xml.transform.stream.StreamResult;




import org.w3c.dom.*;


import org.xml.sax.SAXException;




public class DOMConvert




...{







public static void main(String[] args)




...{


DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();





try




...{


DocumentBuilder db=dbf.newDocumentBuilder();


Document doc=db.parse(new File("students.xml"));





Element eltStu=doc.createElement("student");


Element eltName=doc.createElement("name");


Element eltAge=doc.createElement("age");





Text txtName=doc.createTextNode("王五");


Text txtAge=doc.createTextNode("19");





eltName.appendChild(txtName);


eltAge.appendChild(txtAge);





eltStu.appendChild(eltName);


eltStu.appendChild(eltAge);





eltStu.setAttribute("sn","03");





Element root=doc.getDocumentElement();


root.appendChild(eltStu);





NodeList nl=root.getElementsByTagName("student");


root.removeChild(nl.item(0));





Element eltStuChg=(Element)nl.item(0);


Node nodeAgeChg=eltStuChg.getElementsByTagName("age").item(0);


nodeAgeChg.getFirstChild().setNodeValue("22");





int len=nl.getLength();


for(int i=0;i<len;i++)

String age=nodeAge.getFirstChild().getNodeValue();





System.out.println("姓名: "+name);


System.out.println("年龄: "+age);





System.out.println("-----------------------------");


}





TransformerFactory tff=TransformerFactory.newInstance();


Transformer tf=tff.newTransformer();


tf.setOutputProperty("encoding","gb2312");


DOMSource source=new DOMSource(doc);

}

catch (IOException e)

}




}



其中StreamResult result=new StreamResult(new File("converted.xml"));这是错误的，如果这么写的话，会
有类似如下的异常

java.io.FileNotFoundException: file:/E:/我的项目/DomStudy/src/dom/converted.xml (文件名、目录名或卷标语法不正确。)

我们应该这样写：StreamResult result=new StreamResult(new FileOutputStream("converted.xml", false));
