我的解析xml的代码

        try{
    URL url = new URL(
            "http://myurl.com");
    SAXParserFactory factory = SAXParserFactory.newInstance();
    SAXParser saxparser = factory.newSAXParser();

    XMLReader xmlReader = saxparser.getXMLReader();
    SARParser getTParser = new SARParser(itemList);
    xmlReader.setContentHandler(getTParser);


    InputSource is = new InputSource(url.openStream());
    is.setEncoding("ISO-8859-1");

    BufferedReader br = new BufferedReader(new InputStreamReader(is.getByteStream()));
    String line;
    while((line=br.readLine())!=null)
    {
        Log.i("Line", line);
    }
    xmlReader.parse(is);

               //xmlReader.parse(new InputSource(url.openStream()));

//在谷歌上我找到了这个解决方案，但这给了我错误，因为第 15 行的 token 格式不正确

} catch (Exception e) {
    e.printStackTrace();
}

请帮帮我。如果您遇到过同样的问题，您曾尝试解决什么...请与我分享您的技巧...

谢谢你，马约尔·帕克

Answer 1

您读取输入流两次。

 InputSource is = new InputSource(url.openStream());

这个:

 new BufferedReader(new InputStreamReader(is.getByteStream()));

和

  xmlReader.parse(is);

两者都读取 InputStream，这是不行的。

删除 BufferedReader 和 while 循环(它们只是在那里确认 XML 已经下载你说的)

我找不到支持我的理论的链接。 Best I could find -Reading an IS twice-
