Hi All,
I m just tried XML parsing in Android activity class...When i run the
application i m getting unKnown Error in Screen...
This is my Activity Class
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.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
public class ParsingXML extends Activity {
private final String DEBUG_TAG = "ParsingXML";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
try{
URL url = new URL("http://www.anddev.org/images/tut/basic/
parsingxml/example.xml");
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xmlReader = sp.getXMLReader();
ExampleHandler exampleHandler = new ExampleHandler();
xmlReader.setContentHandler(exampleHandler);
xmlReader.parse(new InputSource(url.openStream()));
ParsedExampleDataSet parsedExampleDataSet =
exampleHandler.getParsedData();
tv.setText(parsedExampleDataSet.toString());
}catch(Exception e){
tv.setText("Error: " + e.getMessage());
Log.e(DEBUG_TAG, "ParsingXMLError", e);
}
this.setContentView(tv);
}
}
And my ExampleHandler class
is
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
public class ExampleHandler extends DefaultHandler{
private boolean in_outertag = false;
private boolean in_innertag = false;
private boolean in_mymytag = false;
private ParsedExampleDataSet myParsedExampleDataSet = new
ParsedExampleDataSet();
public ParsedExampleDataSet getParsedData(){
return this.myParsedExampleDataSet;
}
public void startDocument() throws SAXException{
this.myParsedExampleDataSet = new ParsedExampleDataSet();
}
public void endDocument(){
}
public void startElement(String nameSpaceURI, String localName,
String qName, Attributes atts) throws SAXException{
if(localName.equals("outertag")){
this.in_outertag = true;
}else if(localName.equals("innertag")){
this.in_innertag = true;
}else if(localName.equals("myTag")){
this.in_mymytag = true;
}else if(localName.equals("tagwithnumber")){
String attributeValue = atts.getValue("thenumber");
int attr = Integer.parseInt(attributeValue);
myParsedExampleDataSet.setExtractedInt(attr);
}
}
public void endElement(String namespaceURI, String localName,
String qName) throws SAXException{
if(localName.equals("outertag")){
this.in_outertag = false;
}else if(localName.equals("innertag")){
this.in_innertag = false;
}else if(localName.equals("myTag")){
this.in_mymytag = true;
}else if(localName.equals("tagwithnumber")){
}
}
public void characters(char ch[],int start, int end){
if(this.in_mymytag){
myParsedExampleDataSet.setExtractedString(new
String(ch,start,end));
}
}
}
ParsedExampleDataSet class is this
public class ParsedExampleDataSet {
private String extractedString = null;
private int extractedInt = 0;
public void setExtractedString(String extractedString){
this.extractedString = extractedString;
}
public String getExtractedString(){
return this.extractedString;
}
public void setExtractedInt(int extractedInt){
this.extractedInt = extractedInt;
}
public int getExtractedInt(){
return this.extractedInt;
}
public String toString(){
return "ExtractedString = " + this.extractedString
+ "\nExtractedInt = " + this.extractedInt;
}
}
when i run this application i m getting this error
