How to validate a xml file by an external dtd file?

[yw]

Hi,
I use xerces to parse a xml file, but I don't know how to validate the xml
file with an external dtd file, anyone can help me?

or whether there are some other methods to do this?

Thanks

<!DOCTYPE root SYSTEM "path/to/external/subset">

with "root" being your root element.

Thanks for your answer, I am a novice at XML, can your explain the method
more detailed? and some demo code is better, thank you very much.
