Question

我有以下RSS Parse活动类， package net.snovabits;

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;

import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.Attributes;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.xml.sax.XMLReader;
import org.xml.sax.helpers.DefaultHandler;


import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class AndroidRssReader extends ListActivity {

 private List<String> item = new ArrayList<String>();

 StringBuffer  sb=new StringBuffer();;
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);

       try {
   URL rssUrl = new URL("http://www.fchorgen.ch/?feed=rss2");
   SAXParserFactory mySAXParserFactory = SAXParserFactory.newInstance();
   SAXParser mySAXParser = mySAXParserFactory.newSAXParser();
   XMLReader myXMLReader = mySAXParser.getXMLReader();
   RSSHandler myRSSHandler = new RSSHandler();
   myXMLReader.setContentHandler(myRSSHandler);
   InputSource myInputSource = new InputSource(rssUrl.openStream());
   myXMLReader.parse(myInputSource);

  } catch (MalformedURLException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (ParserConfigurationException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (SAXException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }      

   }




 private class RSSHandler extends DefaultHandler
   {   

  @Override
  public void startDocument() throws SAXException {
   // TODO Auto-generated method stub
  }

  @Override
  public void endDocument() throws SAXException {
   // TODO Auto-generated method stub
  }

  @Override
  public void startElement(String uri, String localName, String qName,
    Attributes attributes) throws SAXException {
      sb=new StringBuffer();

  }

  @Override
  public void endElement(String uri, String localName, String qName)
    throws SAXException {
   // TODO Auto-generated method stub

   if (localName.equalsIgnoreCase("title"))
   {
       System.out.println("--------title------------"+sb.toString());

   }
  }

  @Override
  public void characters(char[] ch, int start, int length)
    throws SAXException {
   // TODO Auto-generated method stub   
   sb.append(new String(ch, start, length));

  }

   }
}

我使用CNN rss URL来获取rss feed，但它不起作用，它显示错误。但是某些URL似乎工作正常。

我也发布了错误日志，

我不知道原因是什么，但我查看XML资源与其他rss feed xml格式相比有所不同。如果有人知道这会帮助我。

感谢。
