Converting Javabeans into XML format

Question

HI,
I have wrote program that will read input from users then stored them in javabeans. I used the serialize function to create xml file from the javabeans.
public static void CreateXML(LocationRequest location)
          try
     // Serialize object into XML
     XMLEncoder encoder = new XMLEncoder(new BufferedOutputStream(
new FileOutputStream("test.xml")));
     encoder.writeObject(location);
     encoder.close();
     } catch (FileNotFoundException e) {
The output file is as follows :
<?xml version="1.0" encoding="UTF-8"?>
<java version="1.4.1_05" class="java.beans.XMLDecoder">
<object >
<void property="address">
<string>21212122</string>
</void>
<void property="originatorId">
<string>Anu</string>
</void>
</object>
</java>
Could anyone has idea on how i can change the above xml file into another new xml format like below:-
<address> 21212122</address>
<originatorId> "Anu "</originatorId>
Cheers,
Bambli

The quickest way would be to use XSLT. Write a stylesheet that converts your 1st format to your 2nd format.
Here's an example stylesheet. (I'm a little rusty on my XSL so you'll want to test this.)
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
    version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" encoding="UTF-8"/>
  <!-- simply copy the message to the result tree -->
  <xsl:template match="/java/object/void/@property">
    <xsl:element name="local-name()">
      <xsl:value-of select="text()"/>
    </xsl:element>
  </xsl:template>
</xsl:stylesheet> Feed this to a transformer as follows:
javax.xml.transform.TranformFacotry factory = javax.xml.transform.TransformerFactory.newInstance();
javax.xml.transform.stream.StreamSource source = new javax.xml.transform.stream.StreamSource(new java.io.File("yourstylesheet.xsl"));
javax.xml.transform.Transformer xformer =factory.newTransformer(source);
xformer.transform(new javax.xml.transform.stream.StreamSource(new java.io.File("yourbean.xml")),new javax.xml.transform.stream.StreamResult(new java.io.File("yourconverted.xml")));Its that simple.
