my code to parse xml

        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()));

//ON GOOGLE I FOUND THIS SOLUTION BUT THIS GIVE ME ERROR FOR NOT WELL FORMED TOKEN AT LINE 15

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

Thank You, Mayur Parekh

回答1:

Your reading your inputstream twice.

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

This:

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

and

  xmlReader.parse(is);

both read the InputStream, that is a no no.

Remove the BufferedReader and the while loop (they were only there to confirm the XML had downloaded anyway which you say it has)

I can't find a link to back up my theory. Best I could find -Reading an IS twice-
