Writing XML with Strings

Here's the code to produce the same output by writing out a String object.

Listing 9-5. Writing XML with Strings

package com.bryantcs.examples.xml;

import java.io.File;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

public class WriteWithStrings {

public static void main(String[] args) {

String xmlContent = createXMLContent();

writeXMLToFile(xmlContent);

}

private static String createXMLContent() {

// write the first line

StringBuilder sb = new StringBuilder();

sb.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>"); sb.append("<poem title=\"");

sb.append(Poem.getTitle());

sb.append("\" author=\"");

sb.append(Poem.getAuthor());

sb.append("\">\n");

// write the middle lines

for (String lineIn : Poem.getLines()) {

sb.append("<line>");

sb.append(lineIn);

sb.append("</line>\n");

}

// write the last line

sb.append("</poem>");

return sb.toString();

}

private static void writeXMLToFile(String xmlContent) {

String fileName = "C:" + File.separator + "test"

+ File.separator + "domoutput.xml";

try {

File domOutput = new File(fileName);

FileOutputStream domOutputStream

= new FileOutputStream(domOutput, true);

domOutputStream.write(xmlContent.getBytes());

domOutputStream.close();

System.out.println(fileName + " was successfully created");

} catch (FileNotFoundException fnfe) {

System.out.println("Couldn't find a file called " + fileName);
