Parsing XML in Android a simple example

This is a simple example showing how to parse an xml in Androi.
In this method the xml file is stored in res/xml folder.

First create a folder named “xml” inside the raw folder.
Then create an xml file named test.xml and copy the contents into it.

<?xml version="1.0" encoding="utf-8"?>
<root>
<name>
CoderzHeaven
</name>
<blog>
 Google
 <sub2>Android</sub2>
</blog>
</root>

This is the XML file we are going to parse.

Now the main.xml file. We place a textView to view the contents of the parsing.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"

  >
<TextView
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:text="CoderzHeaven XML Parsing Demo"
  android:textColor="#FF0000"
  android:textStyle="bold|italic"
  android:textSize="14sp"
  android:layout_margin="10dp"
  />
<TextView
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:id="@+id/xml_tv"
  android:layout_margin="10dp"
  />
</LinearLayout>

Now the main java file that does the parsing.
We use the “XmlPullParser” class to parse the XML

package com.coderzheaven;

import java.io.IOException;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
import android.app.Activity;
import android.content.res.Resources;
import android.content.res.XmlResourceParser;
import android.os.Bundle;
import android.widget.TextView;

public class ReadXML extends Activity {
	@Override
	  public void onCreate(Bundle savedInstanceState) {
	      super.onCreate(savedInstanceState);
	      setContentView(R.layout.main);

	      TextView myXmlContent = (TextView)findViewById(R.id.xml_tv);
	      String stringXmlContent;

		  stringXmlContent = getAllXML();
		  myXmlContent.setText(stringXmlContent);

	  }

	  public String getAllXML(){

		  Activity activity = this;
		  String str = "";

		  Resources res = activity.getResources();
		  XmlResourceParser xpp = res.getXml(R.xml.test);

		  try {
				xpp.next();
				int eventType = xpp.getEventType();
				System.out.println("eventType : " + eventType);
				while (eventType != XmlPullParser.END_DOCUMENT)
			    {
					 if(eventType == XmlPullParser.START_DOCUMENT){
						 str += "nXML Parsing Starting...n";
					 }
					 else if(eventType == XmlPullParser.START_TAG)
				     {
						 str +=  "nroot tag: "+xpp.getName();
				     }
				     else if(eventType == XmlPullParser.END_TAG)
				     {
				    	 str += "nending tag: "+xpp.getName();
				     }
				     else if(eventType == XmlPullParser.TEXT)
				     {
				    	 str += "nvalue : "+xpp.getText();
				     }
				     eventType = xpp.next();
			    }
				 str += "nnXML parsing Ending......";

		  } catch (XmlPullParserException e) {
				e.printStackTrace();
		  } catch (IOException e) {
				e.printStackTrace();
		  }
		  return str;
	  }

	}

That’s all parsing is complete Go on and run the program.
