又一个xml解析的问题, 高分求助!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[djboy]

我的程序如下:

package jp.co.toho.util.xml;

import javax.xml.parsers.*;
import org.w3c.dom.*;
import java.io.*;
import org.xml.sax.*;

class SampleXML
{

public static void main(String[] args)
{
try
{
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
FileInputStream inputfile = new FileInputStream(".\\Sample.xml");
/*while (inputfile.read()!=-1)
{
System.out.println(inputfile.read());
}*/
Document doc = db.parse(inputfile);
doc.normalize();
Element root = doc.getDocumentElement();
System.out.println(root.getTagName());
NodeList mAddress = doc.getElementsByTagName("Address_r");

System.out.println(mAddress.item(0).getFirstChild().getNodeValue());

}
catch (ParserConfigurationException e)
{
System.out.println("Create DocumentBuilder error");
}
catch(SAXException e)
{
System.out.println("Parse Document error");
}
catch(IOException e)
{
System.out.println("IO error");
}




}
}

XML文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<Key>
<Name>
asdasdsadsa
</Name>
<Sex>
asdasdasdadas
</Sex>
<Address>
<Address_r>
fsdasdasdasdas
</Address_r>
<Tel>
afsaasd
</Tel>
<Email></Email>
</Address>
</Key>

现在不管我在xml文件中写什么值, 输出的结果都是:

????

这是什么问题呀, 大家来解决一下.

中间加些错误检查吧，比如文件路径对不对，解析Document doc = db.parse(inputfile);返回的是什么

[djboy]

不太明白, 解析Document doc = db.parse(inputfile);返回的当然是document对象了.

[djboy]

没有人知道吗?

先把这句去掉 System.out.println(inputfile.read());
再试试
