テキストファイルをxmlに変換する方法

Question

このコードは別のスレッドに投稿されていましたが、テキストファイルをxmlに正しくサブフォーマットするように変換することはできません。むしろ出力よりもこのことから、単純なXML

：これに

Example One 
Example Two 
Example Three 

：へ

first_main_elem 
f_child_elem1:one 
f_child_elem2:two 
second_main_elem 
s_child_elem1:one 
s_child_elem1:two 
third_standalone_element: null value 
fourth_element:stand alone 

：

<?xml version="1.0" encoding="UTF-8"?> 
    <inserts> 
    <option>Example One</option> 
    <option>Example Two</option> 
    <option>Example Three</option> 
    </inserts> 

私は、テキストファイルから、次の変換が必要に

<?xml version="1.0" encoding="UTF-8"?> 
    <first_main_elem> 
     <f_child_elem1>one</f_child_elem1> 
     <f_child_elem1>two</f_child_elem1> 
     <f_child_elem1>three</f_child_elem1> 
    </first_main_element> 
    <second_main_elem> 
     <s_child_elem1>one</s_child_elem> 
     <s_child_elem2>two</s_child_elem2> 
    </second_main_elem> 
    <fourth_standalone_elem/> 
    <fifth_element>stand alone</fifth_element> 

コードが掲載さ：この上の任意の提案やアドバイスを

import java.io.*; 
import org.xml.sax.*; 
import javax.xml.parsers.*; 
import javax.xml.transform.*; 
import javax.xml.transform.stream.*; 
import javax.xml.transform.sax.*; 

public class ToXML { 

BufferedReader in; 
StreamResult out; 
TransformerHandler th; 

public static void main(String args[]) { 
    new ToXML().begin(); 
} 

public void begin() { 
    try { 
     in = new BufferedReader(new FileReader("data.txt")); 
     out = new StreamResult("data.xml"); 
     openXml(); 
     String str; 
     while ((str = in.readLine()) != null) { 
      process(str); 
     } 
     in.close(); 
     closeXml(); 
     } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    } 

     public void openXml() throws ParserConfigurationException,TransformerConfigurationException, SAXException{ 

    SAXTransformerFactory tf = (SAXTransformerFactory)SAXTransformerFactory.newInstance(); 
    th = tf.newTransformerHandler(); 

    // pretty XML output 
    Transformer serializer = th.getTransformer(); 
    serializer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4"); 
    serializer.setOutputProperty(OutputKeys.INDENT, "yes"); 

    th.setResult(out); 
    th.startDocument(); 
    th.startElement(null, null, "inserts", null); 
} 

    public void process(String s) throws SAXException { 
    th.startElement(null, null, "option", null); 
    th.characters(s.toCharArray(), 0, s.length()); 
    th.endElement(null, null, "option"); 
    } 

    public void closeXml() throws SAXException { 
    th.endElement(null, null, "inserts"); 
    th.endDocument(); 
    } 
}
