Hi Malathi,
>From this piece of code and the error message in your last email, it still
looks like the problem has to do with the InputStream or Reader that
you're using. Unfortunately, this piece of code doesn't really help debug
the problem, since it doesn't show how the Reader is initialized or the
contents of the XML file that is being read.
You'll get the most help from people on this list if you post a simple,
stand-alone test case that reproduces the problem. Provide a simple XML
file, and a single class with a main method that can be run to show the
error being generated by the Xerces parser. Frequently, in trying to
build such a test case, you'll discover for yourself what the problem is.
Cheers,
