android - XMLPullParser getName() returns null -

i trying parse openweathermap api http://api.openweathermap.org/data/2.5/weather?q=london&mode=xml. using kxmlparser via xmlpullparserfactory.newpullparser() xmlpullparser.getname() returning null. might silly mistake seems might need see it.

here's code read api via httpurlconnection.

 url url = new url(urlstring);                 urlconnection urlconnection = url.openconnection();                 httpurlconnection httpconnection = (httpurlconnection) urlconnection;                 httpconnection.setrequestmethod("get");                 httpconnection.connect();                 if(httpconnection.getresponsecode() == httpurlconnection.http_ok){                     inputstream = httpconnection.getinputstream();                 } 

i used

bufferedreader buffer = new bufferedreader(                             new inputstreamreader(inputstream));                     string s="";                     while ((s=buffer.readline())!=null){                         stringbuffer.append(s);                         system.out.println(s);                     } 

to make sure reading xml , turns out code running properly. next, using following code parse xml

xmlpullparserfactory xmlfactoryobject = xmlpullparserfactory.newinstance();             xmlpullparser myparser = xmlfactoryobject.newpullparser();              myparser.setfeature(xmlpullparser.feature_process_namespaces                     , false);             myparser.setinput(inputstream, null);              int event = myparser.geteventtype();              while (event != xmlpullparser.end_document){                 log.d("xmlpullparserhandler", "sdfdsf " + myparser.getname());                 string name = myparser.getname(); 

but getting java.lang.nullpointerexception @ myparser.getname(); above log showing "sdfdsf null".

what doing wrong?

you can either parse given xml or change mode json , parse json

your xml tag looks like

<city id="2643743" name="london">  // tag name city // id , name attributes values 2643743 , london 

note: have shown parsing of few tags. should understand , parsing rest yourself.

from documantation

public abstract string getname () added in api level 1

for start_tag or end_tag events, (local) name of current element returned when namespaces enabled. when namespace processing disabled, raw name returned. entity_ref events, entity name returned. if current event not start_tag, end_tag, or entity_ref, null returned.

to parse xml , values

public class xmlpullparserhandler {        public xmlpullparserhandler() {      }     public void parse(inputstream is) {         xmlpullparserfactory factory = null;         xmlpullparser parser = null;         try {             factory = xmlpullparserfactory.newinstance();             factory.setnamespaceaware(true);             parser = factory.newpullparser();              parser.setinput(is, null);             boolean check =false;             //factory instantiates object              int eventtype = parser.geteventtype();             while (eventtype != xmlpullparser.end_document) {                  switch (eventtype) {                 case xmlpullparser.start_tag:                      string tagname = parser.getname();                     log.i("tag names ",tagname);                      if (tagname.equalsignorecase("city")) {                          if(parser.getattributevalue(null, "id").equals("264374"))                         {                              string cityname= parser.getattributevalue(null, "name");                              log.i(" city name ",cityname);                         }                      }                     if (tagname.equalsignorecase("coord")) {                               string lat= parser.getattributevalue(null, "lat");                              string lon= parser.getattributevalue(null, "lon");                              log.i("latitude , longitude is","lat= "+lat+"lon= "+lon);                      }                     if (tagname.equalsignorecase("sun")) {                       string rise= parser.getattributevalue(null, "rise");                      string set= parser.getattributevalue(null, "set");                      log.i("sun rise , sun set is","rise= "+rise+"set= "+set);                 }                      break;                  case xmlpullparser.text:                     break;                  case xmlpullparser.end_tag:                       break;                  default:                     break;                 }                 eventtype = parser.next();             }          } catch (xmlpullparserexception e) {             e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         }          return null;     } } 

the log

08-18 16:14:35.885: i/city name is(31634): london 08-18 16:14:35.885: i/latitude , longitude is(31634): lat= 51.51lon= -0.13 08-18 16:14:35.885: i/sun rise , sun set is(31634): rise= 2014-08-18t04:51:39set= 2014-08-18t19:16:53 

also if xml tag looks below

<cityname type="test">city london</cityname>  

to value

case xmlpullparser.text:        text = parser.gettext(); break;  case xmlpullparser.end_tag:        if (tagname.equalsignorecase("cityname")) {                                      log.i("name is",text);        } break;
