//Create transformer
Transformer tFormer =
TransformerFactory.newInstance().newTransformer();
// Output text type
tFormer.setOutputProperty(OutputKeys.METHOD,
“text”);
//Write the document to a file
Source source = new
DOMSource(doc);
Result result = new
StreamResult(System.out);
tFormer.transform(source, result); |
The setOutputProperty method of the
Transformer class set the output key as a text
to print the data on console. Then the
transform() method displays the data source
and the given destination. This program uses
the “System.out” to display the data on the
console.
Here is full source code of GetDomData.java:
import java.io.*;
import org.w3c.dom.*;
import org.xml.sax.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.DOMSource;
import
javax.xml.transform.stream.StreamResult;
public class GetDomData{
static public void main(String[] arg) {
try{
BufferedReader bf = new
BufferedReader(new
InputStreamReader(System.in));
System.out.print(“Enter XML file name:
“);
String xmlFile = bf.readLine();
File file = new File(xmlFile);
if (file.exists()){
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder =
factory.newDocumentBuilder();
Document doc = builder.parse(xmlFile);
System.out.println(xmlFile + “ is wellformed
“); |
|
|
NodeList list =
doc.getElementsByTagName(“*”);
for (int i=0; i<list.getLength(); i++){
// Get element
Element element =
(Element)list.item(i);
//Source src = new
DOMSource(element);
System.out.println(element.getNodeName());
} // Create transformer
Transformer tFormer =
TransformerFactory.newInstance().newTransformer();
// Output text type
tFormer.setOutputProperty(OutputKeys.METHOD,
“text”);
// Write the document to a file
Source source = new DOMSource(doc);
Result result = new
StreamResult(System.out);
tFormer.transform(source, result);
}
else{
System.out.println(“File not found!”);
}
}
catch (Exception e){
System.err.println(e);
System.exit(0);
}
}
} |
Output of the Program:
C:\nisha>javac GetDomData.java

Enter XML file name: emp.xml
emp.xml is well-formed
Employee-Detail
