XML schema namespace problems

[computerbear]

My XML class is kickin my behind. I have an assignment that is to combine 3 files, books, movies and music into one called products. I have xml and xsd doc for each. I have gone over the book and a fellow students work and the solution files. I cannot see what the problem is. This is what I get as validation error:

The root of the document belongs to namespace {http//mediamart.com/books},
but there is no actual DTD, Relax NG Schema, Schematron Schema or XML Schema associated with this namespace.

I have gone over and over character by character comparing with one that validates. What am I missing??? Thank you.

The problem is the schema has a default namespace defined. "xmlns="http://mediamart.com/books""

This means that all elements need to be in that namespace as well. Your XML document has the namespace "xmlns:bk="http//mediamart.com/books" defined. this means that things with the prefix "bk" are in that namespace. But, the document has nothing in that namespace. Everything in that document is in NO namespace.

This can be fixed 2 ways. You can make a document where elements have the bk: prefix, (eg bk:book) or the schema can have the default namespace and target namespace removed.
