Error message from the XSLT Engine

This document had an invalid XSLT Stylesheet.Error message from the XSLT Engine:
Error : invalid use of disable-output-escaping='yes'

I obtained the above error when i try to visit my blog's feeds from the feedburner.Below is the proof,

Solution:
XSLT- Extensible stylesheet transformation is an conversion of xml documents into other output documents such as html,pdf etc.This process requires three main components namely xml source documents,xslt stylesheet and xslt template processing engine.

Here,in xml to html conversion the xslt processor will take two input documents-an xml document and an XSLT stylesheet to produce an output.Where,XSLT stylesheet contains collection of template rules,instructions and other directives to control XSLT processor in the production of output document.

There may be an error in template rules or instructions and in other derivatives. and so it is recommended to check or run the transformation onceagain from the following page,http://www.w3schools.com/xsl/tryxslt.asp?xmlfile=cdcatalog&xsltfile=cdcatalog in order to trace the error.
