I try to parse the xml file in android.
Before that i just implement in java, that code is working fine and i
parsed the xml.
but i can't do the same in android, can anyone help me.
My code in java,
Code:
import org.w3c.dom.*;
import javax.xml.parsers.*;
import java.io.*;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.lang.Byte;
import org.xml.sax.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
public class GetRootNode{
public static final String WEATHER = "weather.txt";
public static void main(String[] args) {
try{
/* BufferedReader bf = new BufferedReader(new
InputStreamReader(System.in));
System.out.print("Enter xml file name: ");
String str = bf.readLine();
File file = new File(str);
if (file.exists()){ */
HttpURLConnection con;
URL url = new URL("http://www.google.com/ig/api?alt=&weather="; +
"chennai");
con = (HttpURLConnection) url.openConnection();
con.setReadTimeout(10000 /* milliseconds */);
con.setConnectTimeout(15000 /* milliseconds */);
con.setRequestMethod("GET" );
con.connect();
// Receiving request is converted into string
BufferedReader reader = new BufferedReader(new
InputStreamReader(con.getInputStream(), "UTF-8" ));
String payload = reader.readLine();
//System.out.println(payload);
PrintWriter out = new PrintWriter(new FileWriter(WEATHER));
out.print(payload);
out.close();
File str = new File(WEATHER);
if (str.exists()){
DocumentBuilderFactory fact =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder = fact.newDocumentBuilder();
Document doc = builder.parse(str);
Node node = doc.getDocumentElement();
String root = node.getNodeName();
System.out.println("Root Node: " + root);
NodeList list = doc.getElementsByTagName("*");
System.out.println("XML Elements: ");
Element element;
for (int i=3; i<=9; i++) {
// Get element
element = (Element)list.item(i);
System.out.println( element.getNodeName() + " : "
+element.getAttribute("data")) ;
//System.out.println(element.getAttribute("data"));
}
System.out.println("\n");
for (int i=10; i<=16; i++) {
// Get element
element = (Element)list.item(i);
System.out.println( element.getNodeName() + " : "
+element.getAttribute("data")) ;
//System.out.println(element.getAttribute("data"));
}
/* for (int i=0; i<list.getLength(); i++) {
// Get element
element = (Element)list.item(i);
System.out.println( i + "-" + element.getNodeName() +
":"
+element.getAttribute("data")) ;
//System.out.println(element.getAttribute("data"));
} */
}
else{
System.out.println("File not found!");
}
}
catch(Exception e){}
}
}
Output:
