Java XML Simple Read Example

To Read and extract the elements from the XML file first parse the XML file though the parser and create the Document
Document doc = builder.parse(str);

Once the document is availabe we can fetch the root and elements as follows
Node node = doc.getDocumentElement();
String root = node.getNodeName();

Example is given below

import org.w3c.dom.*;
import javax.xml.parsers.*;
import java.io.*;

public class GetRootNode{
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()){
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);
}
else{
System.out.println("File not found!");
}
}
catch(Exception e){}
}
}
