Question

Im trying to parse the XML returned by the Google Geo code API ,but im getting the following error while parsing..

 [Fatal Error] :1:1: Premature end of file.
    org.xml.sax.SAXParseException: Premature end of file.
at com.sun.org.apache.xerces.internal.parsers.DOMParser.parse(Unknown Source)
at com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderImpl.parse(Unknown Source)
at javax.xml.parsers.DocumentBuilder.parse(Unknown Source)
at test2.main(test2.java:55)

amd my code is like this.. im sure that im getting the response xml correctly..

        URL u = new URL("https://maps.googleapis.com/maps/api/geocode/xml?latlng=12.983333,77.583333&sensor=false");  
        URLConnection uc = u.openConnection();
        uc.setDoOutput(true);

        StringBuffer sbuf=new StringBuffer();

        inxml=uc.getInputStream();

        BufferedReader in = new BufferedReader(
        new InputStreamReader(inxml));

        String res;
        //System.out.println(" Response from Google Maps "+res);
        while ((res = in.readLine()) != null){
               sbuf.append(res).append("\n");
        }
        in.close();

        System.out.println(" Total Data received  "+sbuf);

        //XML PARSE Starts Here........

        DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();

        Document doc = docBuilder.parse(inxml);

     // normalize text representation
        doc.getDocumentElement ().normalize();

       // System.out.println("Root element of the doc is "+doc.getDocumentElement().getNodeName());

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

please suggest mw some help on this..

Thank u.

Your debugging code is the problem. You read the document to show the xml here

while ((res = in.readLine()) != null){
           sbuf.append(res).append("\n");
    }

which advances the stream past all the data, then you try to read it again with the parser.

If you remove the debug code it should work.
