Output to a file in java

I wanna remove element from xml file, when I run the following code I get the correct output when I'm outputing to console but when I'm trying to ouptup the same code to a file I get the same / original xml file without removed element, here is the code :

Code:

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 RemoveBlock {

  static public void main(String[] arg) {
    try{
      String xmlFile = "Management.xml";
      File file = new File(xmlFile);
      String remElement = "Physical_Order_List_Array";
      if (file.exists()){
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document doc = builder.parse(xmlFile);
        TransformerFactory tFactory = TransformerFactory.newInstance();
        Transformer tFormer = tFactory.newTransformer();
        Element element = (Element)doc.getElementsByTagName(remElement).item(0);
//        Remove the node
        element.getParentNode().removeChild(element);
//              Normalize the DOM tree to combine all adjacent nodes
        doc.normalize();
        Source source = new DOMSource(doc);
        Result dest = new StreamResult(System.out);
        tFormer.transform(source, dest);
       // System.out.println();
       // saveStringToFile("emir.xml", "dsds"); -> write method
      }
      else{
        System.out.println("File not found!");
      }
    }
    catch (Exception e){
      System.err.println(e);
      System.exit(0);
    }
  }
}

The code above is working but when I want to change it to output to a file like : Result dest = new StreamResult(new File("foo.xml")); or Result dest = new StreamResult(new FileOutputStream("foo.xml")); its not working, any indications why ?

Thank you

stag-splitter

STAG-SPLITTER(1p)					User Contributed Perl Documentation					 STAG-SPLITTER(1p)

NAME

       stag-splitter - splits a stag file into multiple files

SYNOPSIS

	 stag-splitter -split person -name social_security_no file.xml

DESCRIPTION

       Splits a file using a user specified parser (default xml) around a specified split node, naming each file according to the name argument

       the files will be named anonymously, unless the '-name' switch is specified; this will use the value of the specified element as the
       filename

       eg; if we have

	 <top>
	   <a>
	     <b>foo</b>
	     <c>yah</c>
	     <d>
	       <e>xxx</e>
	     </d>
	   </a>
	   <a>
	     <b>bar</b>
	     <d>
	       <e>wibble</e>
	     </d>
	   </a>
	 </top>

       if we run

	 stag-splitter -split a -name b

       it will generate two files, "foo.xml" and "bar.xml"

       input format can be 'xml', 'sxpr' or 'itext' - if this is left blank the format will be guessed from the file suffix

       the output format defaults to the same as the input format, but another can be chosen.

       files go in the current directory, but this can be overridden with the '-dir' switch

USAGE

	  stag-splitter [-split <ELEMENT-NAME>] [-name <ELEMENT-NAME>] [-dir <DIR>] [-format <INPUT-FORMAT>] [-outformat <OUTPUT-FORMAT>] <FILENAMES>

       -p|parser FORMAT
	   FORMAT is one of xml, sxpr or itext, or the name of a perl module

	   xml assumed as default

       -w|writer FORMAT
	   FORMAT is one of xml, sxpr or itext, or the name of a perl module

       -split|s NODE
	   node to split on

       -name|n NODE
	   field/element to use when naming files

	   will use surrogate IDs if this argument not specified

       -dir|d DIR
	   write files to this directory
