Thanks for your advice.

The use of SAX filter in server is also inefficient in terms of server.
Because the server must generate large source document, even if filterd
after all.
If a server have a ability to generate a necessary part of source document
on the ground of a client request.
The sever can save a computing resources.
On the assumption a client specify a part of source document in XPath
string.
Is it passible for server to generate a requested part of source document on
the ground of  XML shema (DTD or Schema) of source document?

Thanks in advance
