Xml Parsing Error

Question

Hello All!

I am getting this error while trying to Parse the Xml response from the Web Service by SAX Parser in Android.

ERROR in LogCat :- " Response =====> org.xml.sax.InputSource@43b8e230 " 

I got to know that I need to convert the response in String may be by toString() Method, but the problem is I don't know how to do that as I had tried all the possible ways I knew for conversion but nothing happened.

In InputSource I am passing the url:-

URL url = new URL("http://www.google.com/ig/api?weather=Ahmedabad");
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xmlr = sp.getXMLReader();
DemoHandler myDemoHandler = new DemoHandler();
xmlr.setContentHandler(myDemoHandler);
xmlr.parse(new InputSource(url.openStream()));
Log.e(TAG, "Condition"); 
System.out.println("Response ====> " + new InputSource(url.openStream().toString()));
ParsedDemoData parsedDemoData = myDemoHandler.getParsedData();

Everything is fine but the response I am getting needs to be converted into String which I don't know how to do.

Can anyone please help in this.

Thanks, david

To parse an InputStream you don't have to convert it into a string you can directly read its elements and attributes using Parsers available on Android. You can refer the following links to do the same

How ever if you are looking for a code that converts Input Stream to string something like this will work

 public String convertStreamToString(InputStream is) throws IOException {
            /*
             * To convert the InputStream to String we use the BufferedReader.readLine()
             * method. We iterate until the BufferedReader return null which means
             * there's no more data to read. Each line will appended to a StringBuilder
             * and returned as String.
             */
            if (is != null) {
                StringBuilder sb = new StringBuilder();
                String line;

                try {
                    BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
                    while ((line = reader.readLine()) != null) {
                        sb.append(line).append("\n");
                    }
                } finally {
                    is.close();
                }
                return sb.toString();
            } else {        
                return "";
            }
        }

And this should print the stream for you

System.out.println("Response ====> " + convertStreamToString(url.openStream()));
