使用bufferedreader和delimiter读取多个链接

Question

我正在尝试从文本文件加载多个url rss链接。到目前为止它只能从文件中加载一个链接。我尝试使用分隔符但它似乎不起作用。任何帮助表示赞赏。

代码

    StringBuilder rsslink = new StringBuilder();
    InputStream is = getResources().openRawResource(R.raw.xmlsource);
    BufferedReader br = new BufferedReader(new InputStreamReader(is));
    String line = null;

    try {
        while ((line = br.readLine()) != null) 
        {
           rsslink.append(line) ;
        }
        String [] arr = rsslink.toString().split(";"); 
        for (int i = 0; i < arr.length; i++)
            {
            }
    } 
    catch (IOException e) 
    {
        e.printStackTrace();
    }
    String RSS_LINK = rsslink.toString();

    Log.d(Constants.TAG, "Service started");
    List<RssItem> rssItems = null;
    try 
    {
        XMLRssParser parser = new XMLRssParser();
        rssItems = parser.parse(getInputStream(RSS_LINK));
} 
    catch (XmlPullParserException e) 
    {
        Log.w(e.getMessage(), e);
    } 
    catch (IOException e) 
    {
        Log.w(e.getMessage(), e);
    }
    Bundle bundle = new Bundle();
    bundle.putSerializable(ITEMS, (Serializable) rssItems);
    ResultReceiver receiver = intent.getParcelableExtra(RECEIVER);
    receiver.send(0, bundle);
}

public InputStream getInputStream(String link) 
{
    try 
    {
        URL url = new URL(link);
        return url.openConnection().getInputStream();
    } catch (IOException e) 
    {
        Log.w(Constants.TAG, "Exception while retrieving the input stream", e);
        return null;
    }
}
}

这就是 “;” 作为分隔符的文本文件
