[xsl] XSL output method="text" and indent preservation

[selva <selva@xxxxxxxxxxxx>]

Hi,
I am trying to convert an XML document to a text document. While converting,
I would like to preserve the indentation from the xml source file. I am
using Xalan(1.2.2). The code snippet to convert the XML to TEXT is as
follows.

XMLTextConverter.java
--------------------------------
import java.io.*;
import org.xml.sax.SAXException;
import org.apache.xalan.xslt.XSLTProcessorFactory;
import org.apache.xalan.xslt.XSLTInputSource;
import org.apache.xalan.xslt.XSLTResultTarget;
import org.apache.xalan.xslt.XSLTProcessor;

public class XMLTextConverter {
 public static void main(String[] args) {
    try {
        XSLTProcessor processor = XSLTProcessorFactory.getProcessor();
        processor.process(new XSLTInputSource("myxml.xml"),  new
XSLTInputSource("myxsl.xsl"),  new XSLTResultTarget("mytext.txt"));
    } catch (org.xml.sax.SAXException ex) {
        System.out.println(ex);
    } catch (Exception ex) {
        System.out.println(ex);
    }
 }
}

myxml.xml
----------------
<?xml version="1.0" encoding="UTF-8"?>
<root>
    <myelement>
        <childelement> childvalue </childelement>
        <childparent>
             <grandchild> grandchildvalue </grandchild>
        </childparent>
    </myelement>
</root>

myxsl.xsl:
---------------
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output method="text" indent="yes"/>

<!-- root -->
<xsl:template match="root"><xsl:apply-templates/>
</xsl:template>

<!-- myelement -->
<xsl:template match="myelement">
    <xsl:text>&#x0A;ChildName </xsl:text><xsl:value-of
select="childelement"/><xsl:apply-templates/>
</xsl:template>

<!-- childparent -->
<xsl:template match="childparent">
    <xsl:text>&#x0A;GrandChildName </xsl:text><xsl:value-of
select="grandchild"/>
</xsl:template>

<!-- text() -->
<xsl:template match="text()"/>

</xsl:stylesheet>

Expected output: (Preserving the indentation from the xml source file
-----------------------
    ChildName  childvalue
        GrandChildName  grandchildvalue

Actual output:
-------------------
ChildName  childvalue
GrandChildName  grandchildvalue


How can the indentation from the source xml file can be preserved in this
case. Any pointers please?

Thanks & Regards,
Selva
