java - How to make a program that will download xml data? -

i need make program download xml data website using java program not javascript , put android app.

can me this?

btw next step parse it.

you can use method of read , write !

here code write xml file:

final string xmlfile="userdata"; string username="username"; string password="password"; try { fileoutputstream fileos= getapplicationcontext().openfileoutput(xmlfile, context.mode_private); xmlserializer xmlserializer = xml.newserializer();               stringwriter writer = new stringwriter(); xmlserializer.setoutput(writer); xmlserializer.startdocument("utf-8",true); xmlserializer.starttag(null, "userdata"); xmlserializer.starttag(null, "username"); xmlserializer.text(username_string_here); xmlserializer.endtag(null,"username"); xmlserializer.starttag(null,"password"); xmlserializer.text(password_string); xmlserializer.endtag(null, "password");              xmlserializer.endtag(null, "userdata"); xmlserializer.enddocument(); xmlserializer.flush(); string datawrite=writer.tostring(); fileos.write(datawrite.getbytes()); fileos.close(); } catch (filenotfoundexception e) {  // todo auto-generated catch block   e.printstacktrace();    } catch (illegalargumentexception e) {   // todo auto-generated catch block   e.printstacktrace();   } catch (illegalstateexception e) {  // todo auto-generated catch block   e.printstacktrace();  } catch (ioexception e) {  // todo auto-generated catch block   e.printstacktrace();  } 

read data xml file:

            final string xmlfile="userdata";             arraylist<string> userdata = new arraylist<string>();             try {             fis = getapplicationcontext().openfileinput(xmlfile);             isr = new inputstreamreader(fis);             inputbuffer = new char[fis.available()];             isr.read(inputbuffer);             data = new string(inputbuffer);             isr.close();             fis.close();             } catch (filenotfoundexception e3) {             // todo auto-generated catch block                 e3.printstacktrace();             } catch (ioexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             }         xmlpullparserfactory factory = null;         try {             factory = xmlpullparserfactory.newinstance();             } catch (xmlpullparserexception e2) {             // todo auto-generated catch block             e2.printstacktrace();             }         factory.setnamespaceaware(true);         xmlpullparser xpp = null;         try {             xpp = factory.newpullparser();             } catch (xmlpullparserexception e2) {             // todo auto-generated catch block             e2.printstacktrace();             }         try{             xpp.setinput( new stringreader (data) );             } catch (xmlpullparserexception e1) {             // todo auto-generated catch block             e1.printstacktrace();             }          int eventtype = 0;          try{              eventtype = xpp.geteventtype();             } catch (xmlpullparserexception e1) {             // todo auto-generated catch block             e1.printstacktrace();             }          while (eventtype != xmlpullparser.end_document){              if(eventtype == xmlpullparser.start_document) {                  system.out.println("start document");              }else if(eventtype == xmlpullparser.start_tag) {                  system.out.println("start tag "+xpp.getname());              }else if(eventtype == xmlpullparser.end_tag) {                  system.out.println("end tag "+xpp.getname());              }else if(eventtype == xmlpullparser.text) {                  userdata.add(xpp.gettext());              }              try{                  eventtype = xpp.next();             }catch (xmlpullparserexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             }catch (ioexception e) {             // todo auto-generated catch block             e.printstacktrace();             }          }     string username=userdata.get(0);     string password=userdata.get(1); 

or can save xml sd card

  url url = new url("some url");    //create new connection    httpurlconnection urlconnection = (httpurlconnection) url.openconnection();    //set things on connection    urlconnection.setrequestmethod("get");    urlconnection.setdooutput(true);    //and connect!    urlconnection.connect();   //set path want save file   //in case, going save on root directory of   //sd card.   file sdcardroot = new file("/sdcard/"+"some folder name/");   //create new file, specifying path, , filename   //which want save file as.   file file = new file(sdcardroot,"some file name");  //this used write downloaded data file created  fileoutputstream fileoutput = new fileoutputstream(file);  //this used in reading data internet  inputstream inputstream = urlconnection.getinputstream();  //this total size of file  int totalsize = urlconnection.getcontentlength();  //variable store total downloaded bytes    int downloadedsize = 0;    //create buffer...    byte[] buffer = new byte[1024];    int bufferlength = 0; //used store temporary size of buffer    //now, read through input buffer , write contents file   while ( (bufferlength = inputstream.read(buffer)) > 0 )     {    //add data in buffer file in file output stream (the file on sd card    fileoutput.write(buffer, 0, bufferlength);    //add size know how downloaded    downloadedsize += bufferlength;    int progress=(int)(downloadedsize*100/totalsize);    //this report prgress, maybe     //updateprogress(downloadedsize, totalsize);     }     //close output stream when done   fileoutput.close(); 

hope you..!
