It all depends on how this is represent in the schema. Let's say we have 
the following extended catalog type:

  <complexType name="catalog">
    <sequence>
      <element name="book" type="lib:book" minOccurs="0" maxOccurs="unbounded"/>
      <element name="cd" type="lib:cd" minOccurs="0" maxOccurs="unbounded"/>
      <element name="dvd" type="lib:dvd" minOccurs="0" maxOccurs="unbounded"/>
    </sequence>
  </complexType> 

Then you can have a document that only contains DVDs and you can iterate
over the dvd sequence and copy/move its entries to another document in
the same way as I described in my previous email.

It is hard to understand what you trying to achieve without a concrete
schema fragment. Can you modify the 'library' example to demonstrate
your use-case?
