hi Sébastien,
Thanks for your reply.
What I'm trying to do is - I want to save the result
which is getting displayed on the browser in a file.
So I'm catching the events in XMLSerializer,when I catch the characters event I get
the whole document content inside each element.What I understand is - the
TraxTansformer inputs a ResultSet tree of XML doc to XMLSerializer.
Here is the sample code of XML,XSL and output file --
XML.xml
---------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<page>
<title>Hello</title>
<content>
<paragraph>This is my first Cocoon2 b02 page!
</paragraph>
</content>
</page>
---------------------------------------------------------
XSL.xsl
---------------------------------------------------------
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="page">
<hellopage>
<xsl:apply-templates/>
</hellopage>
</xsl:template>
<xsl:template match="title">
<title>
<xsl:apply-templates/>
</title>
</xsl:template>
<xsl:template match="paragraph">
<para>
<xsl:apply-templates/>
</para>
</xsl:template>
</xsl:stylesheet>
---------------------------------------------------------
The saved file should be -
xmlFile.xml
---------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<hellopage>
<title>Hello</title>
<para>This is my first Cocoon2 b02 page!
</para>
</hellopage>

The XMLSerializer for this is -

I'm getting the xmlFile.xml somewhat like -
xmlFile.xml
---------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<hellopage>Hello
This is my first Cocoon2 b02 page!
<title>Hello
This is my first Cocoon2 b02 page!
</title>
<para>Hello
This is my first Cocoon2 b02 page!
</para>
</hellopage>
---------------------------------------------------------
Hope this helps to understand my problem.
Thanks.

Are you using start and len in public void characters(char c[], int
start, int len)?
Can you send a 5-15 lines code sample where you get the entire content
of your XML
document?
