Hi,

To elaborate a bit I have used Borland xml databinding with a dtd to create classes that read/write an xml doc 
conforming to a dtd. So far so good... if I want to read a whole document or write a whole document then I just 
call the marshal/unmarshal methods of the object representing the document root. 

My question is whether or not I can write/read only part of a document. For example consider a book with 
elements for title, contents, chapters and index. If I have an xml fragment that represents one chapter can I 
use the generated classes to read just that fragment and return a class instance representing that chapter? 
Going the other direction if I have the complete book represented by instantiated classes could I call a method 
(is there such a method) in the class representing a chapter element and have it write out the xml for just that 
chapter? 

Or are things set up when the marshal/unmarshal method for the root is called that are necessary for the proper 
fuctioning of the methods lower in the tree?

An example of why I might want to do this: a user has another app that would generate the xml for a chapter and 
paste it to the clipboard and I would like my app to generate the proper subtree by reading the clipboard 
contents, so that I can just add that child to the existing tree. The real app is more complex but the principle 
is the same.

Thanks in advance!
