Re: Catching XMLSerializer O/P

[Shailendra Vasale]

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 
-


Hello

This is my first Cocoon2 b02 page! 



-

XSL.xsl
-

http://www.w3.org/1999/XSL/Transform";>






  
   

   
  

  
   
 

   


-

The saved file should be -

xmlFile.xml
-

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?
