I cannot read XML data from a particular URL - android

I've been stuck for a while now trying to read XML data from a particular URL. I got a number of material regarding pulling XML Data with SAX and DOM but it doesnt work with my particular URL
Here is the code i tried. This one uses SAX and works perfectly with
TextView name[];
TextView website[];
TextView category[];
try {
/** Handling XML */
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
/** Send URL to parse XML Tags */
URL sourceUrl = new URL(
"http://www.androidpeople.com/wp-content/uploads/2010/06/example.xml");
/** Create handler to handle XML Tags ( extends DefaultHandler ) */
MyXMLHandler myXMLHandler = new MyXMLHandler();
xr.setContentHandler(myXMLHandler);
xr.parse(new InputSource(sourceUrl.openStream()));
} catch (Exception e) {
System.out.println("XML Pasing Excpetion = " + e);
}
/** Get result from MyXMLHandler SitlesList Object */
sitesList = MyXMLHandler.sitesList;
/** Assign textview array lenght by arraylist size */
name = new TextView[sitesList.getName().size()];
website = new TextView[sitesList.getName().size()];
category = new TextView[sitesList.getName().size()];
/** Set the result text in textview and add it to layout */
for (int i = 0; i < sitesList.getName().size(); i++) {
name[i] = new TextView(this);
name[i].setText("Name = "+sitesList.getName().get(i));
website[i] = new TextView(this);
website[i].setText("Website = "+sitesList.getWebsite().get(i));
category[i] = new TextView(this);
category[i].setText("Website Category = "+sitesList.getCategory().get(i));
layout.addView(name[i]);
layout.addView(website[i]);
layout.addView(category[i]);
}
also included in the code is the XMLHandler class that extends DefaultHandler
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
currentElement = true;
if (localName.equals("maintag"))
{
/** Start */
sitesList = new SitesList();
} else if (localName.equals("website")) {
/** Get attribute value */
String attr = attributes.getValue("category");
sitesList.setCategory(attr);
}
}
/** Called when tag closing ( ex:- <name>AndroidPeople</name>
* -- </name> )*/
#Override
public void endElement(String uri, String localName, String qName)
throws SAXException {
currentElement = false;
/** set value */
if (localName.equalsIgnoreCase("name"))
sitesList.setName(currentValue);
else if (localName.equalsIgnoreCase("website"))
sitesList.setWebsite(currentValue);
}
But when i change the url, it returns a XML Pasing Exception = java.net.UnknownHostException: giantstrides.crs.gov.ng and an Unable to start activity error (using Tomcat)
TextView title[];
TextView description[];
try {
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
URL sourceUrl = new URL(
"http://giantstrides.crs.gov.ng/index.php?option=com_ninjarsssyndicator&feed_id=22&format=raw");
/** Create handler to handle XML Tags ( extends DefaultHandler ) */
MyXMLHandler myXMLHandler = new MyXMLHandler();
xr.setContentHandler(myXMLHandler);
xr.parse(new InputSource(sourceUrl.openStream()));
} catch (Exception e) {
System.out.println("XML Pasing Excpetion = " + e);
}
/** Get result from MyXMLHandler SitlesList Object */
sitesList = MyXMLHandler.sitesList;
/** Assign textview array lenght by arraylist size */
title = new TextView[sitesList.getTitle().size()];
description = new TextView[sitesList.getTitle().size()];
//category = new TextView[sitesList.getName().size()];
/** Set the result text in textview and add it to layout */
//for (int i = 0; i < sitesList.getTitle().size(); i++) {
for (int i = 0; i < 2; i++) {
title[i] = new TextView(this);
title[i].setText("Title = "+sitesList.getTitle().get(i));
description[i] = new TextView(this);
description[i].setText("Description = "+sitesList.getDescription().get(i));
//category[i] = new TextView(this);
//category[i].setText("Website Category = "+sitesList.getCategory().get(i));
layout.addView(title[i]);
layout.addView(description[i]);
There is no problem with the URL because it loads the feeds on a browser but i cant get the information i require. Please, i need help, anybody, please..

Parsing XML node having different attribute value in Android

I have following XML data,
<RESPONSE>
<param name="Type">NBFundTransfer</param>
<param name="Id">3213</param>
<param name="Token">26&ffr$5%877</param>
<param name="Stage">1</param>
</RESPONSE>
I want to fetch the node by its name.I use following method to fetch data,
NodeList nl = doc.getElementsByTagName("RESPONSE");
String[] Agreement = new String[nl.getLength()];
for (int i = 0; i < nl.getLength(); i++) {
Node item = nl.item(i);
if (item.getNodeType() == Node.ELEMENT_NODE) {
Element ielem = (Element) item;
NodeList id = ielem.getElementsByTagName("param");
Data[i] = id.item(0).getChildNodes().item(0).getNodeValue();
}
}
But the problem is, Iam only getting the data "NBFundTransfer" from first node which is names as "Type" .I want to fetch the data from all other nodes(Id,Token etc).Please someone help me to get a solution.Thank you..

XMLParsing Sample Project
Here's my output Window -

have a look at this tutorial there is a good guide about xml parsing in android.i hope this will solve ur query
here i am putting that tutrial content
say we need to parse this xml file
http://api.androidhive.info/pizza/?format=xml
and here is a class for parsing this xml
public class AndroidXMLParsingActivity extends ListActivity {
// All static variables
static final String URL = "http://api.androidhive.info/pizza/?format=xml";
// XML node keys
static final String KEY_ITEM = "item"; // parent node
static final String KEY_ID = "id";
static final String KEY_NAME = "name";
static final String KEY_COST = "cost";
static final String KEY_DESC = "description";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();
XMLParser parser = new XMLParser();
String xml = parser.getXmlFromUrl(URL); // getting XML
Document doc = parser.getDomElement(xml); // getting DOM element
NodeList nl = doc.getElementsByTagName(KEY_ITEM);
// looping through all item nodes <item>
for (int i = 0; i < nl.getLength(); i++) {
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element) nl.item(i);
// adding each child node to HashMap key => value
map.put(KEY_ID, parser.getValue(e, KEY_ID));
map.put(KEY_NAME, parser.getValue(e, KEY_NAME));
map.put(KEY_COST, "Rs." + parser.getValue(e, KEY_COST));
map.put(KEY_DESC, parser.getValue(e, KEY_DESC));
// adding HashList to ArrayList
menuItems.add(map);
}
// Adding menuItems to ListView
ListAdapter adapter = new SimpleAdapter(this, menuItems,
R.layout.list_item,
new String[] { KEY_NAME, KEY_DESC, KEY_COST }, new int[] {
R.id.name, R.id.desciption, R.id.cost });
setListAdapter(adapter);
// selecting single ListView item
ListView lv = getListView();
// listening to single listitem click
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String name = ((TextView) view.findViewById(R.id.name)).getText().toString();
String cost = ((TextView) view.findViewById(R.id.cost)).getText().toString();
String description = ((TextView) view.findViewById(R.id.desciption)).getText().toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
in.putExtra(KEY_NAME, name);
in.putExtra(KEY_COST, cost);
in.putExtra(KEY_DESC, description);
startActivity(in);
}
});

Layout Parsing Xml

i'm make example parsing xml from
http://www.androidpeople.com/android-xml-parsing-tutorial-using-saxparser/
in this example, layout using an array textview..
I tried to change the layout into a ListView, but is not working..
I get error in adapter.. can anyone help me?

change your XMLParsingExample.java class
public class XMLParsingExample extends Activity {
SitesList sitesList = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(1);
ListView listVw = new ListView(this);
ArrayList<String> listItm = new ArrayList<String>();
try {
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
URL sourceUrl = new URL(
"http://www.androidpeople.com/wp-content/uploads/2010/06/example.xml");
MyXMLHandler myXMLHandler = new MyXMLHandler();
xr.setContentHandler(myXMLHandler);
xr.parse(new InputSource(sourceUrl.openStream()));
} catch (Exception e) {
System.out.println("XML Pasing Excpetion = " + e);
}
sitesList = MyXMLHandler.sitesList;
for (int i = 0; i < sitesList.getName().size(); i++) {
listItm.add("Name = " + sitesList.getName().get(i));
listItm.add("Website = " + sitesList.getWebsite().get(i));
listItm.add("Website Category = " + sitesList.getCategory().get(i));
}
listVw.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, listItm));
layout.addView(listVw);
setContentView(layout);
}
}
run this code and get all parsing value in listview.
