java - 从资源加载和解析 xml 时出现问题

Question

我已经编写了一个解析器，它从 HttpURLConnection 解析一个 xml 文件。这很好用。

问题:我需要重写这个，以便从本地资源而不是从 Internet 加载 xml 文件，但我无法让它工作...只是让您了解原始 Web 解析器的外观:

InputStream in=null;

URLConnection connection = url.openConnection(); 
HttpURLConnection httpConnection = (HttpURLConnection)connection; 
int responseCode = httpConnection.getResponseCode(); 

if (responseCode == HttpURLConnection.HTTP_OK) { 


   in = httpConnection.getInputStream(); 
   DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();  
   DocumentBuilder db = dbf.newDocumentBuilder();

   Document dom = db.parse(in);     
   Element docEle = dom.getDocumentElement();
   NodeList nl = docEle.getChildNodes();
   for (int i = 0; i < nl.getLength(); i++) {
    Node node = nl.item(i);

    //START PARSING......

现在这是我用来尝试从位于资源文件夹中的 xml/myfile.xml 中的本地资源进行解析的代码:

InputStream in=null;
in = mParentActivity.getResources().openRawResource(R.xml.myfile);

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
                    
Document dom = builder.parse(in); // THIS IS WHERE I GET AN SAXParseException
                    
Element root = dom.getDocumentElement();
NodeList nl = root.getChildNodes();

for (int i = 0; i < nl.getLength(); i++) {
    Node node = nl.item(i);

 //START PARSING......

本地的xml文件和web文件完全一样...如果有人看一下:http://agens.no/Eniro/Android/SEWheel/Category2.plist.xml

这是堆栈跟踪:

02-01 16:08:45.546: WARN/System.err(19703): org.xml.sax.SAXParseException: name expected (position:START_TAG @1:309 in java.io.InputStreamReader@47668728)

找到答案.. 当文件位于 res/xml 文件夹中时，输入流显示大量无效字符。当我把它放在 res/raw 文件夹中时，它工作正常。
