I have read an xml document using XML::Simple in a perl hash.I have accessed multiple sub hashes in my program.But at one line when I try to use a sub hash,it says "not a hash reference".So,what I would like is that if that sub hash exists,it performs one function and if that particular sub hash does not exist,it skips that part.Please suggest.
