Parsing XML from the net

Hi, I am trying to parse a XML from a url using the tutorial that is found in the tutorial section in :

parsing_xml_from_the_net_-_using_the_saxparser-t353.html

For this the class and URL that I'm using is defined as it follows:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 URL url = new URL("http://testing:8082/firma/FirmaServlet?comando=iniciar_proceso&nombre=nombreDelDocumento&proceso=4&url_entrada=http://prestacionesrh50.safp.cl/garest_web/files/102/xml/ge_resolucion200811.xml&url_salida=http://prestacionesrh50.safp.cl/garest_web/generar_resoluciones/recibe_resolucion_firmada.php?idu=102&aaaamm=200811&url_retorno=http://prestacionesrh50.safp.cl/garest_web/generar_resoluciones/resolucion_firmada.php?idu=102");
 
SAXParserFactory spf = SAXParserFactory.newInstance();
                SAXParser sp = spf.newSAXParser();
 
                /* Get the XMLReader of the SAXParser we created. */
                XMLReader xr = sp.getXMLReader();
                /* Create a new ContentHandler and apply it to the XML-Reader*/
                MyHandler Handler = new MyHandler();
                xr.setContentHandler(Handler);
                       
                /* Parse the xml-data from our URL. */
                InputStream stream_url = url.openStream();
                InputSource source_url = new InputSource (stream_url);
                xr.parse(source_url);
                 
                /* Parsing has finished. */
 
                /* Our ExampleHandler now provides the parsed data to us. */
                MyParsedDataSet parsedDataSet = Handler.getParsedData();
 
                /* Set the result to be displayed in our GUI. */
                tv.setText(parsedDataSet.toString());
 
Parsed in 0.032 seconds,  using GeSHi 1.0.8.4

I believe that my problem is that when I use url.openStream() it doesn't open it correctly and I don't know how to fix this. A weird thing is that I noticed is that if I open this url in my computer's browser (firefox) it shows me correctly de xml file, but if I open this link in the emulator's browser it shows a message saying that the web page is not available.

When I run my application the error message that it shows is "Host is unresolved". I hope some one could help me.

I also face same problem. If our html page contains java scripts then it is creating exception. I hope some one will help me to solve this.

Hi, after searching a lot in the web I found no documented answer for this problem. The "solution" that I used to fix this problem came from opening the url on Android's browser and noticing that it generated an error. In my case I analyzed the URL I was handing and noticed that the server name was "testing" word that may be part of the browser "common language" so I change it for the server's ip and all worked perfectly. I hope this helps you to fix your problem.
