Plz remove the error if possible....

But where are the start(), end() and cdata() subroutines? Are you sure you have defined them in your code? As you are trying to pass reference to those to XML::Parser. If they are not defined, XML::Parser on dereferencing them will cause the error. It's not even a parsing error so there is nothing to do with your XML file.

In fact you can repeat the error with something as simple as

Code:

root@xxxxxx:~ # perl -w -e '$a = \&xxxx; &$a'
Undefined subroutine &main::xxxx called at -e line 1.
