I have asked this previously too but this time I have done some research and came back as I didn't get any answer for my problem.I have a data.xml file which has data that I want to give to my android app. I have done the android-end coding and I think its flawless. But the data is not being retrieved from the file into my app. My file structure goes this way
a)data.xml(b)Main(c)HandlingXMLStuff(d)XMLDataCollected(a)data.xml\[code\]<?xml version="1.0" encoding="utf-8"?> <document version="first"> <stuff code="firststuff"> <item1 build="first">This is first item.</item1> <item2 build="second">This is second item.</item2> <item3 build="third">This is third item.</item3> </stuff> <stuff code="secondtstuff"> <item1 build="first">This is first item.</item1> <item2 build="second">This is second item.</item2> <item3 build="third">This is third item.</item3> </stuff> <stuff code="thirdstuff"> <item1 build="first">This is first item.</item1> <item2 build="second">This is second item.</item2> <item3 build="third">This is third item.</item3> </stuff> </document>\[/code\](b)Main\[code\]package com.xyz.xmlpar1;import java.net.URL;import javax.xml.parsers.SAXParser;import javax.xml.parsers.SAXParserFactory;import org.xml.sax.InputSource;import org.xml.sax.XMLReader;import android.os.Bundle;import android.app.Activity;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;import android.widget.TextView;public class Main extends Activity implements OnClickListener { static final String BaseURL="http://www.xyz.com/data.xml?code="; Button b; TextView tv; EditText et1; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); et1=(EditText) findViewById(R.id.editText1); b=(Button) findViewById(R.id.button1); tv=(TextView) findViewById(R.id.textView1); b.setOnClickListener(this); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public void onClick(View v) { // TODO Auto-generated method stub String item=et1.getText().toString(); StringBuilder URL=new StringBuilder(BaseURL); URL.append(item); String fullURL=URL.toString(); try{ URL website=new URL(fullURL); SAXParserFactory spf=SAXParserFactory.newInstance(); SAXParser sp=spf.newSAXParser(); XMLReader xr=sp.getXMLReader(); HandlingXMLStuff doingWork=new HandlingXMLStuff(); xr.setContentHandler(doingWork); xr.parse(new InputSource(website.openStream())); String information=doingWork.getInformation(); tv.setText(information); }catch(Exception e){ tv.setText("error"); } }}\[/code\](c)HandlingXMLStuff\[code\]package com.xyz.xmlpar1;import org.xml.sax.Attributes;import org.xml.sax.SAXException;import org.xml.sax.helpers.DefaultHandler;public class HandlingXMLStuff extends DefaultHandler { XMLDataCollected info=new XMLDataCollected(); public String getInformation(){ return info.datatoString(); } @Override public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException { // TODO Auto-generated method stub if(localName.equals("code")){ String element=attributes.getValue("build"); info.setData(element); } }}\[/code\](d)XMLDataCollected\[code\]package com.xyz.xmlpar1;public class XMLDataCollected { String datac=null; public void setData(String c){ datac=c; } public String datatoString(){ return datac; }}\[/code\]So when I type first or second or third it should retrieve the data. But it does not.What am I doing wrong?
